I won't defend those laws, if you'll agree not to defend the opposite legislation which would force very masculine-appearing individuals into the same women's spaces (obviously scary to the women there), and very feminine-appearing individuals into (scary-to-them, for obvious reasons) exclusive men's spaces. The bathroom issue is an area of easy agreement for people of good will: provide a few private, gender-neutral spaces. Job done.

The activists who talk about non-binary whatever being the apotheosis of humanity are annoying, because the reality is far more boring: transgender experience is a totally normal part of human variation. There's lots of evidence that they've always been a small minority in every society, much like most (all?) other sorts of neuro-divergence. They deserve recognition, dignity, respect, and reasonable accommodation, just like every other human being.

The rhetoric on the other side, however - there are examples linked in this thread, if they haven't all been flagged - is truly dire, eliminationist stuff. It's the same as has said about jews, and many other scapegoated minorities. Regardless of anything else, those sorts of statements must not be made about any human being, in any civilized society.
