The compromise is simple, but they never accept it: purge your party of every single person who got the issue horribly wrong, and we can work together again. Leave a single person in there who still pushes for transitioning kids, and we don’t deal with you.
Leftist political alliances are not separable. They never admit that the whole is intentionally used to strengthen the individual parts.
It’s just like when they throw a riot. Oh no, you can’t hold us ALL responsible when only 2 bad actors were throwing rocks! Even though we let them hide in the crowd so they can escape, or put loud women up front to distract from the men circling the flanks–it’s not fair that you’re tear gassing everyone!
