Um...metal artists (especially black and death metal - imagine that) have been known to do some really crazy things.
Edit: Read your explanation. Just because someone calls themselves a "gangsta" doesn't mean anything, when a lot of the time it's just posturing to sell an image.
I know it's just an image that people portray. I meant it as a joke, don't know why people are getting upset over it. Anyways, as a disclaimer: I do not mean to offend anybody of any race or culture with that comment. It was meant as a joke, and if did offend you, I'm sorry
