I've known trans people since the 80s in one form or other (socially or through work or as my student) And always supported their right to express themselves as they wish. It really is nobody's business.
However no trans woman can live as a woman. They do not have the same common ground as women, they are not subject to the same discrimination, health issues, job prospects or reduction in them, they don't take an average 20% pay cut, they will not have wrecked bodies from childbirth, brittle bones from an early menopause, reduction in pension if they took time away from work to bring up a family etc etc etc.
What they are doing is living as trans women, and that is fine, but different. It is not mean to point out they they do not need smear tests but will need prostate cancer checks.
So I cannot parrot the mantra TWAW as it is not true.
And that is before we get to the authorities putting women and girls at greater risks just to satisfy a vocal minority of activists.
If people stop pushing back on this just so they appear 'not mean', women and girls will lose all the rights they have spent 100 years trying to get enshrined in law. It is unlikely to really affect me, but I can extrapolate and see how it can affect other more vulnerable people. If you think that is being mean then that is your right but it affects every female on the planet and my support is for them, not someone who had all the privileges of being male before they decided to 'live as a woman'.
