Why do Blacks in the US talk differently than Whites ?

[Okay, maybe Mike Johnson is a competent parliamentarian.]

To me, Obama for example seems to talk like the white mainstream, or is it just me as a non-native English speaker who can't hear out the small differences ?

The way Obama normally speaks in public is within the bounds of white mainstream or even prestige sociolects in terms of pronunciation and grammar, but in his stress patterns and word choice one can sometimes discern influence from the oratory style of some black preachers.

Tender, on behalf of Link (because he won't obviously), I apologize for his hypersensitivity.  Such a reaction to racial issues is quintessentially American.

I'd honestly like an answer to my earlier question though.  I've always wondered about it.

The sort of causal racism that is accepted in America is what leads to unarmed black kids getting shot walking home from the store by "frightened" people.

Joe Republic, you are seriously saying it makes perfect sense someone who incessantly posts on the internet about the United States from a foreign country is just now finding out all Americans don't sound the same?  Are you honestly saying you think Michael Jackson, James Earl Jones, Collen Powell, and Barrack Obama sound the same?

Seriously I can take a black person from New York City, a white person from New York City, a white person from Dallas, and a black person from Dallas and the black and white person from New York will sound indistinguishable from each other and totally different than the black or white person from Dallas.

The forum never ceases to amaze.

And yet, you manage to confuse Allen West and Cornel West.
