The constructiveness is going to have to go both ways, with recognition from male people that their distress and need to try and disguise their reality cannot be at the price of them not being that bothered about women's distress and need to be a separate sex class. And that it's not up to women to soothe their distress and hide reality at the expense of their needs and equality. Because that's sexism and oppression just with guilt, coercion and cry bullying.
It is very easy to do third spaces. The blueprint was in the creation of accessible spaces for the disabled, it's been done. You build it into law, you require proportionate provision, you provide government and local authority grants and people to go and spread the word, sympathise that on the surface change is hard and someone's moved the cheese and remind that this has got to get done. And about five years later most places will have them.
People with TQ+ identities will have to accept that societal progress takes time and they cannot just mug women for their resources and let women suck up the exclusion until this happens on the grounds that it's unbearably sad for them but doesn't matter when it's only women suffering. Sadly I've seen way too much of this dominating, inconsiderate and misogynist behaviour. And once third spaces are there at least women who wish to use them are consenting to be in there with males and consenting to the risks they are taking. Their body, their choice. No woman is being forced, no woman is left without accessible provision.
However you will then however have males like Willoughby slamming open the door to the female space to triumphantly declare how female they are being in the female space and quite gleeful really about literally pissing on women's territory and excluding women that they cannot subordinate any other way. And yelling that unless you check their genitals and DNA at the door you can't stop them. And who's going to stand at the door anyway of every woman's space, arguing with a loud, angry, scary and not very well balanced male?
And this is the issue. The thin end of the wedge is a sad male saying please pretend, you don't get how sad I feel, I promise to not hurt you, just be kind a little bit. The middle end is males excluding women and shouting that they are female, so lesbians pants off and line up, and women who won't be props in their fantasy will be punished by exclusion/for hate crimes. And the end is Isla Bryson and co raping and harming women in women's spaces. But they are all the wedge. The thin end is just opening the way for the others.
So the appeals for pity aren't doing much really. We've tried compromise. Men with and without gender identities broke it. Women's boundaries and needs are nowhere on the radar. And no one cares how they feel. It is at this point highly sexist to require they continue to bend and trust and sacrifice out of pity for male feelings about this. My sympathy now is entirely with women and their needs, and their best interests. Because if I don't care, no one else is going to do it for me or worry about making me sad.
