I like a music group whose sound is incredible but whose lyrics are extremely pro-white. Should I not listen?

You sound like an educated guy so you must know the answer to this one. Are you asking for permission to ease your guilty feelings? Personally speaking I do take a stand on some things and there's no way I'd get any kind of enjoyment out of racist music. I wouldn't watch a film by child sodomiser, Roman Polanski either. It's called having principles my friend.
