Those studies about people with "white" names getting twice the number of callbacks for job interviews weren't in-person affairs with obnoxious people. They were basically a boss being handed two more or less identical CVs, but one had a "black name".
Also, I'm curious: do you think prejudice against blacks ended when slavery was abolished? Maybe after the civil rights movement? When did it become blacks being irresponsible and wanting handouts, in your mind?
That's called racial profiling and stereotyping, and it's racism, despite your claims to the contrary.
That you equate African-American or otherwise black names with the "ghetto" is quite telling. Why can't these people just have "proper" names, right?
Not all black people act like this, but it's still much harder for blacks to get jobs and the like (and those are the one who aren't necessarily gangsta).
Which names are respectable, exactly? Who decides that?
When you stereotype blacks as a whole as being "hood" or otherwise not having "respectable" names, and then say this is part of why they're struggling... well, what do you expect the response to be?
