I’ll put it to you this way then... Why do blacks feel the need, and it is a quite recent need, to go around punching out White people?
Blacks only punch white people?
Are you saying that every black on white crime is the knockout game?
They have a black man as President, a black Attorney General, there's affirmative action in both education and hiring, hate crime laws, anti discrimination laws, etc, etc.
And the lives of lower-class blacks still suck.
It's either decide that (A) all whites, as a class, have the unchangeable will and power to keep blacks down, or (B) accept that maybe it's their own fault that they have shitty lives. And they cannot accept (B).
