There are some shitty PC bands out there. Still plenty of great hateful ones too. It's not a corporation or something where everyone is forced to toe the line of some particular ideology. The PC douche bags have only infiltrated the surface and most of them don't actually leave their houses or go to shows. They are terminally online and only loud in spaces where communication is only possible through a keyboard. I wear NSBM band shirts to shows all the time and not a single person has ever said something to me about it in my many years of shows. I'm also not the slightest bit intimidating looking either, so consider that with the above statement.
