"I rather think the crux of this issue for many, if not most, females is ignored.
In humans, as in all mammals, female has a distinct meaning. That meaning obviously has a limit, a boundary, as does the distinct meaning for male.
Any man declaring himself to be a woman, ie: female, violates the boundary of the meaning of the sex class that is female. It is a violation of the integrity of the sex class that is female.
This violation, occurring as an assertion of male power over females, is against our female consent.
It is a blatant deceit on all women and girls to use 'she' or 'her' when referring to any man who pretends he is not a man, whether it is considered a matter of courtesy or not.
It is a blatant deceit on our entire society for any law to state that a man can become a woman.
Women are very angry about this violation and this deceit."

"Why is it “common courtesy” to pander to people’s fantasies that they have changed sex? ? Is it also “ common courtesy” to pretend to a skeletal anorexic that she is too fat because she wants you to say she is? In both cases you are participating in a lie."

"When it went from being a courtesy to an enforced obeisance, everything changed."
