An inclusive way to be gender critical?

I'm sorry OP, I've read your post 3 times but I'm really not sure what you're trying to say. I agree with your premise about gender and sex being different, I agree with your conclusion about everyone being free to dress as they please whilst still segregating based on sex in some circumstances, but your argument in the middle totally lost me. You want to redefine gender to mean "male/female" instead of "masculine/feminine" and then redefine "male/female" to mean "anybody regardless of how they dress"? I don't see how that helps protect single sex spaces? Do you just mean that men need to be more inclusive by accepting feminine men in their spaces, and that would eliminate the demand by feminine men to enter women's spaces? If so then yes I agree that men should be more inclusive to other men, but it won't reduce demand to enter our spaces because for a decent number of transitioning men the goal is to make women feel uncomfortable or to feel "validated". Maybe some are motivated by a genuine fear that they will be unsafe in male spaces, and would be happy to use male spaces if they could feel confident the other men there would be welcoming and inclusive, but I think they're in the minority. Apologies if I interpreted your OP wrong.

You are also using ‘female’ for both social roles and reproductive function, so likely to cause confusion.

I don’t see how what you say is more ‘inclusive’ than most GC positions. At the end of the day, a male can’t become female, certainly not by self-declaration, and if you include males in the category of female, the category itself no longer makes sense. I’ve gone through the arguments many times but there is no way around this basic fact. Women can either accept it or be nice and embrace their status as illogical doormats. Sorry.

Great. I think there is only sex. I don't believe in the concept of gender. Everything outside sex is personality.

What are female fashion and interests. Are you saying I am not female because I wear doc martens, combats, hoodies, have short hair, like driving, F1 and doing my own DIY?

Can you not see how regressive stereotypes like the ones you say should be definitions are? We should be breaking down these stereotypes not reinforcing them.

A man who likes make up and dresses and sewing is no less a man or male any more than I am any less a woman or female for not liking them.

But I am a woman who has short hair, wears only jeans and boots. My sex is female and my gender is female. Presentation does not equate with gender.
Stereotypes are regressive and should not be encouraged.
