I mean I think it's a thing. So many people have so many different ways to describe their sexuality I don't think it's useful to gatekeep them, it's better to just accept all labels by default and only narrow them down if you have a specific reason for doing so.
The ableism instinct I also get, but think that applying it in such a personalized way is unhelpful. Imagine calling gay men misogynist for not being attracted to women. Individualized application of discriminatory terms like that is a form of liberalism.
