You misunderstand nersnerr
It's not just self ID I have a problem with - I've been posting on this long before that came on the radar
It's also not trans people I have a problem with - in general although seeing cunty women switched out for trans people all over the place is not good - it's sexism
I have a problem with the fact that women & girls are still an oppressed group in societies all over the world to a greater or a lesser extent, and for years feminists with the occassional male ally have been campaigning fighting advocating for, where we need them, rights, laws, services that were not in place because societies everywhere are based in a male view of the world and what they need and want.
IF we accept that a male person can be included in the group women / girl / female, then we have NO umbrella term for the most basic categorisation of our species, the first and most important thing we knew even before language, and that is, the ones that impregnant, and the ones that gestate.
IF there is no group word for these groups, then they cease to exist, at least in language and in law. While in fact, they continue to exist, and 99.9% of people in the world know very well which is which and will continue to treat them accordingly.
Thus we continue to have misogyny and sexism, but the language to identify and discuss it has been removed.
And I don't think this is an accident. Which charities and services are being trageted as being "exlusionary"? - It's all ones aimed at women and girls - FGM, period charities have come under fire. Feminists must not fret about biology but about "femme oppression". The crime stats are changing - which set are changing most? Women's of course - the men's estate losing a few makes no odds, the women's gaining a few especially violent / sex offenders completely skews the female crime stats and makes focussing on the problem of male violence harder. And so on and so on.
Make no mistake that this all impacts negatively on the group formerly known as women and now known as (?).
As one TIM said - "enjoy your erasure".
