Yeah it sucks, unfortunately this is how any community where the personalities of it’s most influential members can be shortened as “contrarianism” is destined to end up. A lot of Metal was just edge for the sake of edge, and this allowed fascists to creep in by hiding behind that sense of contrarianism.
Yes, unlike Metal, Punk’s contrarianism had a political message, one which pushed most fascists away.
I actually prefer Metal to Punk, in fact I listen to more Metal music than any other genre else these days, but I really despise most Metal fans.
