Who is saying it doesn't exist? What's sad in this country is that some seem to think that only "white folks" can be guilty of it.
Such issues as hatred and discrimination originate in the "heart". And the last I heard, people of all colors and ethnicity have one. When we realize that in this country, and quit with the one-sidedness, that some how white people can be the only ones guilty of such, while other minorities cannot be because of past, historical transgressions committed against them, then we can move forward in real dialogue.
