I think every group that's been at it for many years has conflicts, but do the fans of other bands get as heated about them as we do? Do Beatles fans say "f--- that McCartney for wanting to reverse the writing credits to McCartney/Lennon"? "That Ringo is just a talentless hack making money off his luck at being part of the greatest band in history?"
Of course they do. Any fandom in general is the same, really. Nobody can hate like a fan hates! Normal people just shrug and move on.
"Joel is better than Mike and I'll FIGHT ABOUT IT!"
"Take that back about Colin Baker! He was a great Doctor! Moffat is sh*t!"
"John Cale's solo albums are clearly superior to Lou Reed's, you stupid bastard!"
