There's also a fringe undercurrent of lesbianism being fine/ in some cases preferred (eventually...there was a lot of lesbian and bi erasure early on)
Yes; see Shulamith "what do you
mean this radical feminist house party doesn't have men at it to hook up with?!" Firestone, for instance.
but a very conservative take on male homosexuality being wrong as it includes sexual gratification and the expression of sexuality without women and is therefore misogynistic (long forgotten groups like Redstockings etc)
That's the natural conclusion of some of the crassest "penetrative sex is rape" or whatever takes, yeah; the more people involved in the sex act who are capable of penetration, the rape-er it is.
While fringe some of that does rear it's ugly head online (there's a great account on twitter about Gender Critical homophobia) in recent years. Especially around issues of surrogacy and adoption.
I know MRDA to me saying this, but I don't think surrogacy and same-sex adoption are really equivalent issues, even though homophobes often attack them as though they are. There are pretty straightforward "orthodox" feminist arguments against the former, even if one doesn't agree with those arguments, which there really are not against the latter.
