No worries, and me too. :)

The binary trans will eventually just say, "That was just the radicals saying that, not us," or blame nonbinaries entirely.

Yeah, that's true. There is already this sentiment among the "truscum" subgroup of trans-identified people. (Ironically, many of those people are straight and AGP/AAP. Not that it's any better when a gay/bisexual person feels pressured to transition out of internalized homophobia!)

A lot of nbs, in my opinion, are future transphobes or will just be vocal trans critics, and I fully expect to see a wave of former nb people talking about how they regret transitioning or simply leaving the community in the next 5 years.

Yeppp. And I'm inclined to wonder whether a bunch of them might just go switch to a different ideology that denies reality. The post I linked with Helena the formerly-nonbinary-identifying detransitioner is a good example of your prediction.
