I understand why it might seem strange if that’s your only reference point for lesbian but he him lesbians doesn’t necessarily mean they are men but could also just be using masculine pronouns of he him with a different gender identity. Trans men also use lesbian sometimes since they previously used lesbian before transitioning, which is ultimately fine
I think that you’re failing to understand that people can use he/him pronouns and not be a man. Butches, non binary people, GNC people, all sorts of people may identify somewhat with masculinity (or just prefer he/him pronouns for whatever reason) but feel that lesbian is a more suitable label for their sexual identity. It’s not really your job to decide if someone meets the “standards” of the identity they claim or not. Welcome to queerness, it’s not always black and white.
It changes the dynamic of a relationship and structure of a lesbian relationship to replicate that of a heterosexual couple. One partner is seen as the “man” The other partner is seen as the “woman” This unintentionally reinforce the stereotype that relationship needs masculine and feminine roles, which is a traditional heterosexual assumption. While it may be to make the he/him individual more comfortable truthfully it’s because of societal norms that dictate what it means to be masculine
You could say that about any gay/lesbian couple that ever has one stay home and one work or that has a more masculine presenting or feminine presenting one. You could also say this about a bisexual person dating someone of the opposite sex. Being similar to a normative heterosexual couple doesn’t make something harmful unless the relationship itself is harmful.
masc4femme relationships have literally always existed in lesbianism. two queer people loving eachother is never heterosexual in nature, and i find it strange that a lot of people have this idea in their head that lesbianism has to go hand in hand with femininity. butches and trans masc people have always been a huge part of the lesbian community, and that literally just isn’t heteronormative???
