I was wondering why this was posted here until I got to the last sentence and I think I now understand how OP screwed this up so badly.

I don't really need people implying any and all AFABs attracted to women as the only valid lesbians

AMABs attracted to women are heterosexual males <--- this is what they don't want. They have to be "lesbian" in order to not be dudes. I think this is it. It's not just them framing their attraction from the locus of their gender identity and abusing language, as it appears on the surface. Instead, it's about the validation of their gender identity. They're not really talking about their attractions.

"Lesbian" isn't just who they like, as "woman" is the erotic target for AGP. Being "lesbian" is important, because only women can be lesbians. If they're a lesbian, they're a woman.

This gets really tricky because in order to understand what lesbian is--and how it could appeal to them--you have to really, deep down, throw away the gender woo woo, understand that lesbian is a homosexual woman-born-woman. Whilst pretending in a different corner of your brain that that's applicable to yourself when it obviously isn't the case.

I know I mentioned cognitive dissonance on a different thread, but this is such a perfect example.

Festinger argued that some people would inevitably resolve dissonance by blindly believing whatever they wanted to believe.

And it's from here that you probably get "TWAW," if you predicate that before reading OP's post, it makes sense.
