I'm with Khandu on this one — there are few things I find more offensive than the PC morons who haven't figured out that words are not their enemies. If you're that squeamish about reality (past or present), then maybe folk music and blues are not what you really want to sing, since they deal with a lot of the nitty-gritty of life.

That said, of course, you're free to do anything you want — even if it makes you a jerk.

cheers,
