I haven't seen the show but the setup in this scene makes Meg looks like the correct side
she was. it was the episode where she blasts the family about their abuse and it ultimately makes them dysfunctional. after that brian sits her down and convinces her to be their "lighting rod" or somesuch, saving the status quo. this liberal, being typically evil, probably remembers all this and admires both that and the rich aristocratic version of the others
