Leftists and trannies have been part of AF for a long time, unfortunately. If you followed him on twitter, you would see them orbiting his posts, oftentimes mad he didn't "go all the way" on an issue they like. I think they want to groom him, since he is an influential figure that is naive about a lot of things and not very political. He doesn't know how leftist activists work, and now that he opened up a discord, they have a perfect avenue to finally transition him and his community into "one of their own". His wife being an emotional retard all-in on LGBT doesn't help.
Sad, but what can you do. He's been teetering on the edge like this for a long time now. Let this be a lesson for the fence sitters: If you don't pick a side, eventually, the side picks you and there is little you can do about it.
