I mean if i was kyle gass id tell jack black to go fuck himself. He made a big fit over a simple joke when his whole shtick(before being a literal clown for Disney(tm)) was being an 'edgy' comedian who writes songs that are supposed to be offensive.
And the song continues to tell about the destruction of the government, with the implication that previous leaders are dead. It's obviously a joke song, and when KG made the joke on stage it should have been taken just the same, but Hollywood Jack stepped in and thought about all of the movie deals he was gonna miss out on... like fucking Minecraft... Yeah. I love Jack, and I wish him the best, but I am on KG's side, and if they haven't fixed this shit on a personal level, and Kage comes out with some shit about Jack sucking, I'm gonna wave goodbye to the D.
He said something, as he was making a birthday wish on stage, to the effect of “I hope the next shooter doesn’t miss”. For context it was like 2 days after the first Trump attempted shooting
