Their American fanbase (yanno, the MASSIVE group of people that enabled the Dixie Chicks' success... it sure didn't come from European audiences) turned on them because their values were obviously different and I guess Natalie Maines couldn't grasp that.
I don't have any evidence, but I'm leaning towards thinking that the people calling for Joe Rogan's cancellation aren't his main fanbase. That's the common thread with today's "social liberal" influence on media- people that are complete non-consumers of whatever winds up in the crosshairs just go to fucking war nowadays against whatever they've decided is offensive.
