That's fine, no one here is suggesting they do speak for all women.
However, it is not bigotry to protect women's rights, or single sex spaces, groups, prisons, sports, awards, etc etc etc.
The fact is that women need those things, and no woman or women have the right to give them away for all women either.
The law as it stands supports the women who want their own rights, single sex spaces, etc and so on.
If you have a problem with this (what you call hatred and bigotry), you are not going to change the mind of any one who believes this is right.
It does not help those trans identified men who you think are so hard done by, by the law upholding women's rights, single sex spaces etc etc, to shout at women who you say are displaying their "awful and hateful bigotry" by agreeing with the law and sharing a sense of relief that, reluctantly begrudging though it was, the WI is to be a single sex group like it is supposed to be.
You could be doing something useful to help those trans identified men, who you say are most vulnerable and marginalised, but instead of choosing to help trans identified men do something, you have chosen misogyny.
You'd rather come and scold us and call us names and tell us how horrible it is that the law agrees we can have our fucking rights, groups and everything else back from the men who crept in by stealth, politically and socially, and stole them away.
