Most TRAs are very clearly left or far-left, given their support within those spaces, their adoption of communist ideology and their use of postmodernist rhetoric. I will extend an olive branch though: given how insane TRA rhetoric actually is, I think one could reasonably make a case for them not technically being left-wing. Especially the overlap the male trans community has with incels is a clear case of horse-shoe theory. I would be open to such an argument. And then of course there's the cases where some of them, again particularly male trans people, straight up identify as nazis and far-right. So I'd agree with you to some point, but it's still undeniable that TRA ideology is very clearly a left-wing ideology, though one that conflicts with some other left-wing ideology. (After all, nobody would argue radical feminism not to be left-wing despite its friction with many other left-wing ideologies.)
