"Freedom of expression vs. Negative influence on people" is the line that's been drawn. Some bands do go over that line and I can think of a few that as good as their music is, the message is too negative or dark to want to be a part of. A gimmick is one thing. Spreading a message of hate is another. I think some of these bands forget that the world is not the US of A where freedom of speech is in the Constitution.
