AOG - //Pardon me if I inject a little common sense here, maybe they are from the same country, but for example there are Pakistanis in this country also, but our cultures are miles apart. //
yes but we are not talking about Pakistanis in England, we are talking about a black man in America, so your analogy is baseless.
Let's not over-assume based on the evidence, but I would be wiling to bet that this young man did not disembark from a banana boat last week, so I think his 'cultural' assimilation can be taken as read. I bet he speaks English and uses a knife and fork and everything!
