Black people who call other black people "Uncle Tom, and white people who call other white people "N Lovers" are the real racists - not necessarily those who hold a different world or political view.
my favorite part of that documentary is where it talks about how rush limbaugh attacked colin powell for voting for obama and pointed out how racist it was to accuse him of only voting for obama b/c he was black. the documentary points out how limbaughs remarks and his comment that ‘Melanin Is Thicker Than Water’ is a form of reverse uncle tom-ism.
