I read the piece - what a pompous, unmitigated pile of horseshit.
I have slid back and forth between the white and black cultures for my entire life and I have been discriminated against more by blacks than I ever did by whites.
Blacks are one of the only groups of people I know who discriminate against other members of their own race for not being "black enough."
I have been excluded and marginalized because of my skin colour for as long as I can remember. Whites where always much less prone to actively discuss it or use it as a barometer to judge me.
Don't get me wrong, there are plenty of racist white people in the world, it just isn't condoned or well tolerated by other whites.
