The far left actually has often been historically at odds with LGBT people and recently our worst detractors are called “TERFs” or “Trans Exclusionary Radical Feminists”. I can also attest that some of the most hostile folks in any crowd that comes to one of the readings for my memoir are far lefties who are “against the binary”. I can usually spot them in the crowd, they are usually women with their lips set into a straight line, terse with anger way beyond any skepticism. They are the “queer women” who dislike me for being “too binary”.
So really, trans people have the rare and odd privilege of being denigrated by certain actors on both the left and the right — there is no pleasing everyone and sometimes anyone at all.
