Whereas female people are about 50% of the population and in some situations, not just physical but also social, professional and cultural, we face signifcantly different experiences, risks and challenges to male people because of our physical sex and the way our culture's mores and expectations are still shaped by the sexism of the past.
So we should be able to allowed to sometimes define ourselves by our sex, as people who share the same needs because of our sex instead of people who all the same sort of mixed sex hand wavy gender/personality type.
It should not be controversial to say that since we face sexism because of our sex, and sexual assault because of our sex, and bear a higher physical, social and often economic cost of raising children because of our sex, we have the moral right to mitigate these things.
And it should not be controversial that at times that can include saying we only want to compete in sports with people of the same sex, or we only want to be touched for intimate treatment or care by someone the same sex, or we only want to be counseled or supported by someone of the same sex, or we only want to be in spaces we are partially clothed or otherwise in a state men are known to fetishise with someone of the same sex, or we want to create a professional support network or training or one to one mentoring that is specific to our sex and the challenges of our sex to create opportunities for our sex.
And these things should not be considered to be somehow an act of hate or rejection of trans women because ultimately it's nothing to do with trans women and whatever they feel about themselves and what is fair to them, it's about what female people need and what is fair to us.
And if the rights trans people are asking for cannot allow for this, the problem is not with women, the problem is with what they are asking for.
