John represented what liberalism used to be, not the Frankenstein monster now known as Leftism.
People say Yoko and/or John broke up The Beatles. . .honestly I think Paul did a lot more damage because of how radical he became.
John while being opinionated kept things civil as best he could.
Ringo just wanted to have fun and entertain people . . .and yes, Caveman is one of the best comedies ever made. The closet he got to politics lately was supporting Brexit.
Paul on the other hand. . .good grief. Whenever there was some 'cause' in the 1980s-1980s and even early 2000s there he was in the thick of it trying to remain relevant.
