This very much lays bare all your rationales.

You equate pointing out the lack of recognition for autonomy, which is an empirical statement about the human law, with an affirmation about the inherent capacities of autonomy, which is an empirical statement about biology.

You lay bare that you think your tribe's prejudices are laws of nature.

Of course, as Dante pointed out, the human law imposed limitation in many ways seeks to be as universally applicable as biological limitations would be. It seeks to be compared in scope and inevitability. And by it, it reduces the room for choice also inevitably. Not by biology (and physics) but by the actions against the exercize of materially valid biologies.
