There are stories in the news all the time about school principals trying to ban certain bands' shirts from the school (Slipknot, Cradle of Filth, and Marilyn Manson come to mind...) because those bands "promote unhealthy ideals" or some such bullshit. Usually those schools are out in some backwater part of Kansas or Missouri...the same schools where the parents insist that they teach the "God created everything in seven days" theory in addition to evolution theory. So you know how the rest of us feel about those people.
Oh well, I'd support a ban on Slipknot and Manson shirts though...if only because they suck!
