Free sample - The White Power. translation missing

The White Power. The White PowerWhite power is a collective term used to describe white racial movement as they dominate almost every thing in the United States of America. This can be illustrated by looking at Ku Klux Klan, the name given to three different ancient and current supreme organizations in the United States. These clans are said to have boomed in different times (Leeper, 2000) .For example, the first Klan boomed in the years 1860s and became in existence in the 1870s and it was only available on the southern parts with their white costumes consisting of makes and robes. The second Klan came into existence in the early and mid 1920s while the third was known after the famous Second World War with their unforgettable records of practicing terrorism, a tactic that is believed to have been boosted by the second KKK. History holds that, during the reconstruction of Radical republican, the first Klan sought to restore superiority by engaging in criminal acts characterized by murder and so much violence against the blacks and white Republicans. This led the Federal government to put force acts, which advocated for the Klan prosecution (Leeper, 2000). The second Klan is said to be very different from the first Klan as it was a formal organization with its activities practiced country wide. This Klan taught about clean politics and advocated for Unity in American states. One of the biggest criticisms to this Klan is the fact that, some local groups went to extremes of attacking civilian houses and did other unnecessary violence. When you compare the history of these Klan’s you find that, the third Klan caused a very high destruction ,as it is believed to be responsible for the historic bombing of Birmingham 16th street Baptist church, that claimed lives of   so many civil rights workers and innocent children(Leeper,2000). Today many people believe that, the KKK is a rebellious organization as declared in 1999 by the city council of Charleston, in southern Carolina and the unforgettable campaigns made by the University of Louisville professor in the year 2004 to have the Klan declared illegal organization, so that it may be abolished from the campus. Currently the Klan is said to have so many members after the 2008 election of President Obama.The main objectives of the current membership is based on rising issues of illegal immigrants and increase of urban crimes.

Critical Social Analysis Essay Example | Topics and Well Written Essays - 750 words

Critical Social Analysis - Essay Example The basic assumption of the article underlined the fact that the privileges enjoyed by the whites deliberately override the basic rights and freedom of persons belonging to different color of skin, culture and religion. The repercussions of such discriminations are extensive and often abusive for underprivileged segment of society living in extreme poverty and sub human conditions in various parts of the world. The condition in South Africa is worth mentioning because of the abject poverty which has resulted in HIV/AIDS pandemic. As per the article, out of 3 million cases, 2.4 million HIV/AIDS cases were in Africa only! The writers are appalled that such human misery has, neither evoked empathy among the rich nations nor has it penetrated their hard faà §ade of self interest. One of the major ideas that the article propagates is that of health being one of the fundamental rights of all persons. Health is incorporated in the 1946 constitution of WHO2 and 1948 declaration of Human Rights. They clearly state the need for a minimum standard of living and access to medical facilities, food and housing for every human being, irrespective of race, religion, political belief and socio-economic conditions. The concept has been accepted in theory but practical implementation has yet to take off. The callous attitude towards the less fortunate can be gauged by Andrew Natsios, USAID Director when he said that Africans should not receive lifesaving AIDS treatment because ‘they don’t know what Western time is’(Salim). This is most blatant expression of racism at its worst not because of its offensive content but that it is uttered by a man of authority who is fully aware that he will get away with any blasà © attitude because he is white and he is American. America indeed, has turned out to be the biggest promoter of global apartheid. The inequalities and discriminatory practices are a legacy

Medeas situation Essay Example for Free

Medeas situation Essay Dogan people in the city who didnt believe Cassandra because she was an outsider. In this play it  was learned that sometimes the most insightful people are the outsiders because they are not blinded by the normal activities of the main characters.  Another minor character that foretells the future is Medeas nurse in The Medea. The Nurse has a different situation than Cassandra. She is more familiar with Meadea and her children and knows of their daily activities. She begins to have insight on Medeas situation when Medea starts to see a change in her relationships between Jason and her children. She first foretells the murder of Medeas children, who were indeed murdered but by Medea herself. In the very beginning of the story, the Nurse talks about Medeas dwindling love for Jason. But now theres hatred everywhere, Love is diseased.  (Greene, Lattimore, Euripides I, 59)  With her love for Jason waning, she begins to think less and less of her children because they remind her of him.  She has turned from the children and does not see them./I am afraid she may think of some dreadful thing,/For her heart is violent. (Greene, Lattimore, Euripides I, 60)  With her heart violent, she doesnt think anymore of the children except to carry out her evil plan which is to kill Creusa. Another quote that shows the deterioration of Jasons and Medeas relationship is the conversation that the Nurse and the Tutor were having. And will Jason put up with it that his children/Should suffer so, though hes no friend to their mother? (Greene, Lattimore,  Dogan 4  Euripides I, 61)  The Nurse is showing her concern here when she asks about what would Jason do about his children since hes not in love with Medea anymore. Towards the end, it is subtly made known that Jason only wanted the children as heirs to the throne that he did not take because Medea killed Creusa. The Nurse may not have foreshadowed as much as Cassandra did, but she gave the reader an idea of what was going to happen to the children.  In conclusion, minor characters do have some meaning plot-wise. They are not blinded by the everyday life of the main characters allowing them to see the obvious without the help from others. Without them, the story would be mainly about two or more parties and their actions minus the suspense that the minor character gives the reader.

Stem Cell Research - Embryonic Stem Cells Save Lives :: Persuasive Argumentative Essay Examples

Embryonic Stem Cells Save Lives    Special cells that are taken from human embryos, called embryonic stem cells (ES cells), actually possess the power to save your life. These cells can serve many medical purposes and have the ability to benefit people in infinite ways. The importance of embryonic stem cells rests in their lack of specialization. These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body. Being self-renewing, they offer a potentially limitless source of cells and tissue. (Tucker) The versatility of these unique cells is what makes them so valuable and vital to human existence. They have properties that no other part of the human body can possess. One example of how ES cells could work is Parkinson's disease. Parkinson's is caused by the death of cells in the brain that produce dopamine. Placing ES cells in the dopamine-producing region of the brain could cure Parkinson's. That is just one of the many possible effects that ES cells could have on serious diseases, among other things. The importance of this relatively new discovery, even though not yet realized by everyone, could have already played an important part in the lives of a majority of the people. I am one of those people and can actually relate a personal experience that has made me a strong believer in the importance of ES cells. I am sure that there are many people who have had experiences much like my own who can, by relating back to their own personal experiences, comprehend the significance of ES cells in today's world. But if ES cells can prevent life-threatening diseases and save your life, why is the government banning research on them? The uniqueness of these special cells has caused a huge amount of controversy in not only the medical world, but also in politics and wherever else the topic has been discussed. It is to be expected that there are going to be risks associated with the study and use of ES cells. Some who are opposed to researching ES cells argue that it is wrong to experiment on human embryos because it prevents the possibility for human life to evolve from those embryos. Another major reason ES cells are under so much controversy is because of the possibility that the cells could be used for purposes other than producing cells and tissue to help treat disease, like cloning.
