Seems he wasn't at all contrite and the now-deleted "apology" was meaningless.
Kyle Gass of Tenacious D has deleted his Instagram apology following intense backlash over a controversial comment about former U.S. President Donald Trump during the band's Sydney concert. The fallout from Gass's joke led to a domino effect that saw Gass dropped by his agent, and the remainder of Tenacious D's tour was canceled.
Ehhh, fuck him then. I thought maybe he was one of the not so bad guys. Figures...
