i think people are only comfortable doing whats culturally acceptable no matter what color/race. look at black hockey players.. in canada its culturally accepted so you see a bunch there. black tennis players are few and far between and seen as isolated cases. you dont exactly see brazilian boxers, but mostly brazilian mma fighters right?
but i do think black people suffer most from this, from the anti-intellectualism (which seems to be more ingrained to race identity rather than the actual idiocy in white people) cause its so much easier to insult someone for not being "black enough" and lets be honest how many little kids are visionaries like that.
think Grams post was a bit unfocused and unspecific. there's poverty then there's culture.
but yes grams, to confirm your thoughts, most black people are lazy and dont want to work, so they're too poor to afford.. hockey equipment
edit: only one way to settle this, OFT-Funded community hockey rink in deepest poorest black part of Alabama
