It doesn't bother me. More power to them. I don't care too much for the rap rock thing. I always thought they were really funny, even when they were being total dickheads, it was entertaining. It's like watching a cartoon.
Music is a very emotional thing.
They thought Elvis was the spawn of the devil. Seems this is the same dumb as mentality. If you were like 'go kill each other' maybe a case could be made. Sometime you beat yourself up and sometimes you just play. It's not like play when you recite the same lines.
