In many ways you're right, but even back then parts of Lesbian seperatism had shitty, shitty takes. Janice Raymond was openly transphobic before it was cool and was ostracised from many Feminist spaces because of it. Dworkin had to put down Biological essentialist views as early as the late 70s (Warning, some SWERF shit here. Dworkin had some very traumatic experiences as a sex worker, and it resulted in a problematic but not entirely unsympathetic opposition to any and all sex work and pornography)
