I, too. Bisexual women like me were once their natural allies. But if Gender purists and TRAs have lost the support of women, then that's their fault, not ours.
Perhaps they genuinely believed that they could claim we are bigots, tell us who we can and can't be attracted to, erase our status as women from medical literature, reduce us to our anatomy; that they could assign to us labels we don't consent to like 'cis' and then insult us on the basis of those labels; that they could take it upon themselves to inform us rape victims need to 'reframe your trauma', or that lesbians should 'get over your genital fetish'; that they could assume any non-compliance with this systemic, institutional, social bullying justified them in hounding us out of our jobs, threatening to dox, rape and kill us, or using the police to pursue and intimidate women who were saying what they didn't care to hear.
Perhaps they thought we'd suck all that up under the pretext of performative allyship, sit up and beg them for another good old kicking so that we can claim our rainbow lanyards, pronoun badges, and nice little accolade as a good, well-behaved liberal 'feminist'.
And when women said 'to fuck with that' they act all surprised and immediately start with the DARVO.
Fuck it. Fuck all of it. THEY created this particular TERF, and I'm getting to the point where I'd wear that badge with pride (albeit not the pride I remember ...)
