I'm probably not the best person to give a concise rundown, but the most succinct way I can put it is,
-all the "post-left" hipster-libs bap gave his blessing to have brought in a tranny with them
-this tranny keeps showing up at post-left/nrx/whatever you want to call it IRL events, in positions of prominence, no less
-people point out, "hey, it's real fucking weird you're platforming a tranny and giving him a position of prominence in all this stuff"
-the post-left/nrx/braposphere people get incredibly defensive over the tranny, keep beating around the bush and avoiding the actual question of why a tranny is being elevated in that space
