in the 1960s and 70s there was a similar moral panic about lesbians, and a rejection of lesbians as women and as belonging to feminist groups by a vocal minority of second-wave feminists, very similar in some ways to the current moral panic about trans women and the vocal minority of TERFs.

It’s such a weird emotionally driven thing though. At one point I was putting on a lesbian barbecue…. Weirdly enough (a lesbian couple was our neighbors and I’ll do a cookout for anyone). Most were great people but a couple stood out

• One was a hulking butch type who lifted weights. Nearly my size and clearly stronger: great person to talk to and comfortable in her body and presentation
• Another was her opposite, tiny with delicate features but excessively masculine and really just trying hard to be a man, took my presence as a challenge. I found that a strange experience and could never be comfortable chatting with her. Maybe she wanted to transition I don’t know but it was just excessive and overwhelming any personality she may have had. It’s not just that I found nothing in common or there was any way it could threaten me, but i definitely felt uncomfortable in ways I was not proud of
