Or, instead of blaming it on a drop of black blood, we could just admit that it's not black people who are the problem but rather the culture of violence fostered in the ghettos and helped along by white liberals who try to convince them none of this is their fault, they are trapped, their lives can't get better and even glorify their lifestyle

The problem isn't blacks per say, but rather the "ghetto black culture", the culture that promotes violence and racism against whites.
This culture is self destructive, and so racist that they don't care when blacks are killed by blacks but instead care only when blacks are killed by non blacks. Only then that murder is a travesty. Stalin was right.
Attacks by blacks are on the rise, and have been for years. Nothing is being done to stop these black flash mobs who show up, beat some people, then leave. Some get caught, most get away. I blame society for letting these people get away with this, so they think beating up random folk is ok, so they take it to the next level, killing someone, because nobody did shit to them for jumping all those people or beating up random folk.
That culture is toxic and we need to put an end to it because whites are exterminated from the inner cities alltogether. Another round of white flight will happen unless whites start retaliating.
