I don’t think there’s a real problem outside of the same groups that tend to be TERFs to call yourself lesbian if you are technically bi/pan but lean towards women as partners.

I’ve never had a lesbian complain about me calling myself lesbian despite being attracted to all genders. I have only ever experienced straight people complaining about the technicality. But I do know there is that weird way of thinking out there that bi women are really straight and just wanting to experiment. I haven’t dated a man in probably a decade, though I have made out with a couple of them. I just don’t often have romantic feelings for men. Sexuality and romantic alignment are rarely binary. It’s mostly those who are questioning their own alignment and want to deflect who like to complain about others.
