I'm too old to talk about 'dating', but yeah, if I met, say, a GNC GC male, I might think he was attractive, with both the GNC and the GC playing a role.
I'd also find a bloke who accepted and behaved as if women are humans too, quite attractive. I see more of that from some GC male allies (no, not thinking of Glinner but some smaller voices) than I do from the genderists, who appear to think 'woman' is a free floating concept defined by its lack of definition.
I can think of one or two transwomen who acknowledge and behave as the above, so I wouldn't neccessarily say no to a 'date', given the afore-mentioned love of male GNC as an aesthetic, but hormonally treated and/or post-op would be hard no, as would if the person was in a bad way with their dysphoria. I've put up with enough 'being good to the struggling male' in my life without wanting to do it any more.
But in theory ? Transwoman who acknowledges her maleness, is engaged in deconstructing her more toxic masculine attitudes, is a feminist ally, presents in a feminine way but handles her social and/or physical dysphoria without medical intervention ? Okey doke.
To be clear - for me, the 'no' has nothing to do with someone feeling or presenting in a feminine way while male.
The no would be around 1. not respecting females and female experience 2. wanting to be treated as a woman while exhibiting toxic masculinity via attitudes and behaviours towards women 3. active and ongoing psychological distress - person is not ready for relationship 4. health issues arising from hormones/ me prefering male bodies without obvious breasts 5. me preferring male genitals over women's.
If someone can't accept the above as valid and wants to consider that bigoted, I can't stop them. I checked my conscience, and my conscience thinks the above is both accurate, open, and fair (to myself as well as the hypothetical trans person).
