Their rationale is "GC people and LGB people who want to drop the T are a bunch of angry internet trolls who have no lives and are taking their anger out on the trans community. Just like incels." This reasoning is false -- I've met many more successful GC feminists than successful trans people. I've also heard the trans community say that detransitioners aren't real and that detransitioners are a bunch of internet LARPers who are astroturfing to strike fear in the general public about transitioning.
