This feels like bait. If you’re serious, then go up the chain of command. Everyone has a boss. Your sister’s counselor should not be trying to convince your sister that her brother needs to change. Your sister’s counselor really should have no opinion of kids not under their charge, and if she does have an opinion, she should keep it to herself.
You and your sister probably have more allies than you suspect.
The crazy part about Fetterman is that he wasn’t tied down by the Democratic leadership. They backed McCormick, a pro-business centrist, during the senate primary, and they didn’t want him as lieutenant governor before that. He was a progressive wildcard that touted his independence from the party. He was always pro-Israel, but he was also pro-healthcare for all, pro-marijuana legalization, supported human rights and a progressive tax code. His heel-turn has been shocking and baffling, and lost him most of his supporters. Fetterman could be primaried from the left or yhe right, and he will probably lose either way. He could switch parties, but there aren’t enough batshit Republicans in PA to make up for his flaws.
