Obviously you affiliate with Republicans (as did I until relatively recently). Why do you feel the need to defend someone who discredits your group by openly believing bonkers things?
Also, how effective do you think your tactic of "label-outgroup and dismiss" is? It's not persuasive at all except to those already persuaded.
The party leaders are defending the people you say discredit the party. McCarthy has spent more time and effort attacking Liz Cheney than Greene. And Greene claims Trump supports her. Does this look more like a party rejecting bonkers, a party undergoing a purge of disloyal members, or a party caught like a deer in headlights?
And how bonkers is she really? This stuff isn't new. American Nazis at Madison Square Garden in 1939.

WWII put a damper on that movement. Bonkers suggests crazy or outlandish. If Greene had a mental health problem, she'd be harmless.
