Biased?
I am curious as to why it would seem that the U.S was singled out for a complete page on national racism? - I have yet to find a page dedicated to racism in other countries such as Africa, Britain, Mexico, Brazil, Iran, etc etc. 

Why is it that a whole page is dedicated to racism in the U.S as if it is/was the only country to marginalize persons by race?

I believe that this page should be merged into a general page of world racism, or just be deleted altogether, it's a little more than "biased" in my opinion.  

See Racism by country. We deal with the "bias" of missing articles on Wikipedia by writing new articles. See WP:CSB if you want to help provide a more global view. By the way, people who say Africa is a country might raise a few hackles among other editors writing about racism. 

The situation in the United States is unique in terms of its special brand of racism, the completeness of the...the campaign against Native Americans, the special circumstances surrounding the trans-Atlantic slave trade, the particularities of this version of slavery, the premises and outcome of the Civil War, and especially the complex time period following emancipation. This period is fairly unique in many ways, including but not limited to the fact that a bifurcated society developed with the former slave class developing in parallel alongside the former slave-owning class with visible distinctions in terms of melanin and linguistic distinctions resulting from the circumstances of the previous centuries, the long process of segregation, Jim Crow, the rise of African-American influence on mainstream American culture, KKK, White Citizens Councils and lynchings, and the long drive for the abolition of Jim Crow and the securing of the right to vote not only on paper but in practice, and the fact that many of the goals have been achieved, though how thorough this achievement has been is still a topic of debate. Most historical precedents result in one race wiping out the other, either by killing or displacement. To merge this article would be like merging an article on the Second world War into a general article on War, or merging the article on Homo Sapiens into an article on mammals. It makes no sense.
The truth hurts, but it's still the truth. This is a website for facts.

I see where you hesitated with the ellipsis.  The American campaign against the Natives involved such things as biological warfare, enslavement, mass rape, forced migration, and ordinary massacres. It was nothing less then genocide.  —Preceding unsigned comment added by 75.132.84.67
