I have not known a single butch (or even just slightly tomboy) lesbian irl who is now age 35 or younger and HASN'T at some point identified as a man or non-binary. Many of them have taken testosterone. It's a social contagion. Young lesbians would go to college seeing themselves as lesbians, see a bunch of the butch lesbians start to identify as men starting with those in gender studies and spreading outwards, and they would see this trans narrative as the explanation for why they felt different, and then so many lesbians were identifying as trans that new lesbians would get male pronouns assumed and have a bunch of people asking whether they'd started T yet, etc. Speaking from personal experience. We lost the role models who showed us that being a masculine woman is not a pathology, including some older women 50+ I've known who transitioned to "straight men" in the last five years after a lifetime in feminism and proclaiming pride as a butch lesbian. Now this seems to be starting in high school more often as it's gained prominence on social media sites and more generally, and affecting more straight girls too.
