This is very insightful and I see you're already getting strong pushback. It illustrates the challenges inherent in any progressive movement and the natural inclination to revert to power structures that, in any combination, look strikingly similar.

We see it in the electoral politics of the USA where you would hope the black vote would be for progressives yet is only now going that way. When it comes to transgender its becoming accepted that gender is a construct but we forget that so is race.

You've rightly pointed out that without being intersectional, all liberation will revert to rigid and oppressive structures in which the persecuted can seemlessly become the persecutors.

Another issue that I see (which won't make me popular) is that, at some point, infinite self identity will implode. There will need to come a point where the differences become unimportant; but that can only be resolved by creating a society that doesn't make the differences necessary.
