I feel like this isn't really something many cis lesbians would agree with. A lot of cis lesbians are very much attracted to trans men and a lot of straight trans men prefer to identify as lesbians. And it has always been this way.
A surprising number of cis and trans lesbians are full-service sex workers so lesbians do absolutely fuck men, even if it's just for money.
I'm not even going to mention how widespread the conversion "kink" is among both cis and trans lesbians.
But in the end "lesbians are not attracted to and don't fuck men" is really only true as a transmisogynistic dog whistle, same as having a "genital preference" because let's be real, the only genital preference that exists is one that excludes both pre-op and post-op trans women.
Lesbianism doesn't really have any meaning beyond "AFABs attracted to AFABs" and I don't think this will ever change.
