yeah, thats certainly part of it but there is a little more to do it than that

hockey is cool, i used to think it was lilly white but its not really, the same way that white fools who only dig hockey and golf are racists, black people that only dig basketball and football could be thrown into the same boat

but otherwise i agree with what you're saying about assimilation and hued hierarchy/colorism. i thought i was the only one noticing a lot more black girls with white dudes. oh well, i cant cry about that trend but i suppose its part of the grander assimilation movement...
