I feel like we don't talk enough about how "cis men genuinely identifying as lesbians in good faith" not only exist, but are often just closeted, questioning, or unaware of their true gender. As in, they're not actually cis men.
Hell, sometimes they're literally just trans lesbians who are open about their identity as women/genderqueer* people, but get misgendered and thrown into the "cis man" category. Did we all forget about how "men can't be lesbians" is a transmisogynistic dogwhistle?
Cis men (or "cis men") earnestly calling themselves lesbians are probably genderqueer.* And even if they aren't, who cares? It doesn't affect you. And if they're "identifying as lesbians" with the intent of trolling you or harassing you, you will likely be able to tell by additional information.
- If someone insists that you have to give them a chance sexually/romantically because "I'm a lesbian," they're either not actually a lesbian, or weaponizing their identity against you. Either way, this is harassment. Identifying in a certain way doesn't give you the right to date or have sex with someone, even if you're identifying that way in earnest.
- If someone insists that you have to give them a chance sexually/romantically because "lesbians can be/like men," the same applies. Some lesbians like men, or are men themselves, but this is not always (or even usually) the case. Even when it is the case, consent is imperative. Bi lesbians and lesboys still have the right to say "no."
- If someone is generally homophobic/lesbophobic/transphobic, does not typically identify as a lesbian, using their "identity" as a weapon, and is not taking themselves seriously, they're probably trolling. You know those videos where Steven Crowder pretends to be a woman as a way to dunk on actual women (especially trans women and their allies)? It's like that. You can tell they're trolling because the "identity" is satirical and inconsistent with their usual beliefs and actions.
Notice that "identifying as a lesbian" is not the problem in any of these points. The problem is their behavior, and their weaponizing of the lesbian identity.
I'm a trans man. I used to identify as a lesboy because I wasn't confident in my manhood, and have since moved past that. I don't consider myself a lesbian (nor sapphic) now, and I also wouldn't date anyone who identifies as a lesbian, because it would make me dysphoric.
I was wrong about being a lesboy, but being wrong about it didn't make the exclusion feel any better. I was working through my shit, and was met with exclusion and suspicion in many cases. When I identified as a lesboy, what I needed was a supportive, inclusive, and accepting community. What I often got instead was derision, exclusion, and debates over my "validity" as a lesbian. Sometimes I was treated like a predator, or like I was "invading" a safe space for lesbians. (Does this sound familiar?)
I fully support people's right to earnestly identify as lesboys/lesbian men, whether that's as a stepping stone to their true identity, or just reflective of their complicated experience with gender and attraction.
I think that there's something to be said about identifying as a lesbian when a man you're attracted to feels uncomfortable with that. I strongly believe that you should either change your label at that point, or be quiet about your attraction to them, because misgendering people through your label is still misgendering.
This is true even if you identify as a lesbian in a way that is inclusive to men (e.g. bi lesbian, lesboy), because the word still has strong woman-centric connotations (similar to how calling someone "girl" in a way intended to be gender neutral can still be misgendering). People have expressed attraction to me while identifying as lesbians... It doesn't feel good. If you're attracted to me while continuing to identify as a lesbian, don't tell me, because I don't want to know. I don't care if I'm "the exception" because that still sucks.
Still, I don't think manhood is always outright incompatible with lesbian identity, whether you're attracted to men, or a man yourself. The only thing that matters is how the person experiencing the attraction, and those they're attracted to, feel about it. These things are not always so cut and dry, and I would rather accidentally include the wrong person than accidentally exclude the wrong person.
And yes, if you're inclusive of AFAB lesboys, but not AMAB lesboys, this is transphobic. Basing inclusion on AGAB is transphobic. To the people who think they're being inclusive or enlightened by saying "trans men can be lesbians, but not cis men," I want you to think real hard about what you're implying. Trans men do not have an inherent "closer proximity to womanhood" than cis men. Likewise, trans women do not have a "closer proximity to manhood" than cis women.
*I use genderqueer as an umbrella for "anyone with a queer relationship to gender," including those who are trans, nonbinary, GNC, or otherwise subvert the cultural gender expectations placed upon them at birth/during development. In other words, having a queer gender modality, identity, or expression.
