you're asain, fam and it sounds like you deal with a lot of losers if you're still hearing that as an adult.
denzel washington, e lee, obama and even tim duncan all speak with intelligence and grace and nobody says they "sound white". "sounding white" =/= speaking intelligent. you gotta be a dummy if you believe this. the only time people get called out for "speaking white" or an uncle tom is when you abandon your race and culture for the acceptance of non blacks, like charles is doing.
again, this crab in a bucket is specific to youth. socially awkward kids, nerds, geeks, emo goth kids, will always get talked about and picked on while the good looking, athletic kids will get praised even if they're lacking mentally. that goes for all races.
barkley needs to pick up a book and learn how to read before he judges anyone. if he wasn't blessed with athletic ability this coon would be serving my dinner or flipping burgers somewhere.
