I'm just getting this niggling feeling that these arguments are so impervious to logic that I'm not sure any more what is gained by dismantling them.
This is true. I've posted before about how support for trans ideology, especially from women, is based on deep-seated emotions and desires. The feeling of pity for a man who seems like he has been cast out from manhood. The longing to be in solidarity with men and the sense of flattery when one of them declares that he wants to join 'team woman'. The shame at being one of the lowly humans with female biology and the wish for that biology to not matter as much as it does, or at all.
All the ridiculous arguments about how DSDs disprove the sex binary and all gender is socially constructed anyway are just covers for the fact that 'trans women are women' is a catechism, a faith-based position, and like all faiths, it is based on our deepest longings.
The biggest threat that is climate change( and degradation of the earth and all of its other life forms) is precisely because women are instinctively and symbolically connected to Mother Earth, to nature and its rhythms; to the body.........As you say women are expected to take up this great nourishing, nurturing, protective role - even against their own best interests. To be self sacrificing.
This is another big, unspoken dynamic. The equation of 'woman' with 'nature' is almost entirely unconscious on the part of most people, but it informs all views on sexual politics. And the thing is, it's not entirely wrong. Women are more obviously connected with nature and the animal world because of pregnancy, birth and child-rearing. Of course, the truth is that all people are part of nature, we are all inseparable from our biology, but I think it's easier for men to forget this.
