I would add that gender nonconformity doesn't necessarily equal 'people are different.'
Gender is society's rules and expectations imposed upon people, particularly women, which then tries to maintain this is a result of their sex. Rather than their socialisation.
So women should be compliant, feminine, submissive and lady like.
So when men wear make-up and frocks and act feminine, and, crucially maintain this must mean they're women, they are underpinning the gender stereotype.
Whilst, simultaneously, their socialisation remains the same and their actual behaviour is as gender conforming as can be. Dominating women, ignoring boundaries, feeling entitled to, and demanding access to, what's not theirs. It doesn't get more stereotypically 'male'.
Transgender ideology ensures that men fulfil society's gender expectations from start to finish.
What would be gender nonconforming is if man wore what they liked, including feminine clothes, but still called themselves men, did not demand access to things that are women's, and advocated for women's rights. (And not in a transparent, self serving pretendy way, that gc women can spot at fifty paces).
