Discovered recently that Electric Wizard were kinda dicks back in the day. “At the time, we were pretty bad people. I got arrested for arson of a car, outside a police station. Tim [Bagshaw] went to nick a crucifix off a church roof so we could use it onstage…”
R. L. Burnside killed a man “possibly at a craps game.”
Varg of Mayhem Burzum burned a couple churches and killed a bandmate.
I could list other examples, but would like to hear from other people and other music genres.
It’s a bit more complicated. Only some specific tribes consider this a slur. Other tribes do not. There’s nothing offensive in the term itself (it’s not pejorative) so it’s more about using one term for different tribes that don’t consider themselves to be members of the same group.
