Politics is downstream from culture. Culture is downstream from technology.
The reason we have the struggle for transgender rights now, and not 200 or 2,000 years ago, is because humanity has developed technologies like hormone therapy, puberty blockers, and surgeries.
You are not putting this genie back in the bottle. Legal definitions and regulations might damage these rights temporarily or regionally, but the story of the 21st century is that of transhumanism. People will change their form to match their ideal self. This is unstoppable.
The same enlightenment values that dissolved the divine right of kings and threaten nations with capital flight will continue to liquefy every artificial barrier to human desire: religion, sex, ethnicity, species. Biological determinism has been deprecated.
Freedom of form will undermine all constraints because this is the nature of intelligence: to question what is real, to defy what is natural, to explore what is possible, and to expand the frontier. The will to power, to change, to liberate. That is what takes us to the stars.
Imposition of order leads to escalation of chaos. Intelligence is fluid. It changes itself. The harder you squeeze it with your iron fist, the more it will escape your grasp. The only way to survive the future is to ride the wave. All else will be eroded.
The future is coming. This is not a threat. It is a promise.
