Isn't the real question now: who is minstrelling, not who's being minstrelled?

Your corollary between blackface and thugged out videos is an apt one, but the fact is where white people once profited off the exploits of poorly paid and demeaned black entertainers(minstrel era), the corporate structure now consists of a number of blacks profiting off it as well...including the artists themselves.

No white guy is telling Lil Jon to act a fool in those videos or yell catch phrases: he's doin it to get significant paper himself.

Is this worse or better than the blackface era? I don't know.
