What they continuously fail to appreciate is that they are flying counter to the societal trend of accepting a wider range of gender expression. You don't want to call a man a woman just because he wears a robe, a kilt, or a cardigan from the women's side of the store. You don't want to call a woman a man just because she buys men's dress shirts and wears pants. You still accept that a guy is a man even if he puts on makeup or lip balm or has a boyfriend. A girl is still a woman even when she sits with her legs apart and acts butch.
What they're demanding is, "judge everyone based on rigid, traditional gender norms and assume gender based on that" (while reeeing on social media about people assuming their gender online).
As for the makeup thing (which I've commented on before), I think it's an indicator separating real dysphoria from autogynephilia. Someone who genuinely wants to be a woman as an identity thing, not as a fetish, not as a result of autism, not as a radical identity change due to mental illness and escaping reality – will recognise that women have female friend groups and try to fit in with other (natty) women, asking for help with a 'makeover', and observe and listen to women to try to be more like them. They follow the advice of female beauty gurus on youtube like natty women do, not of transadvocates on twitter. Obviously, those aren't generally the ones you find in online trans communities.
The autogynephiliacs, on the other hand, express the most negative stereotypical masculine traits as 'women': they demand everyone (especially women) cater to their fetishes and whims and put their own needs and feelings aside; they expect recognition and praise regardless of how little effort they put in; and they refuse to listen to women, feeling that they have nothing to learn from women because they presume they know better. Being a woman is just about being kawaii, weak, helpless, submissive, and pampered, right? Easy! (And now I see how the Adult Baby fetish ties into transgirl identity...)
