I think that's right. Some AGP men really are dysphoric and it's not fair to say they're not "true trans" while at the same time accepting extremely feminine gay men who like to act out femininity as such. There are plenty AGP men who never cross-dress out of their own home and haven't the slightest intention of transitioning, too.
It seems more as if there is a toxic combination of AGP and narcissism which isn't a terribly uncommon mix, and these guys become super-obnoxious and entitled. They're also extremely high-profile and vocal and often gravitate to be the leaders of the TRA movements. I suspect also that exposure to these guys can suck other less extreme personalities into their orbit.
These guys are a fairly small subset of everyone who identifies as a transwoman but they're vocal and active and they are the ones driving the movement and influencing the authorities, so they're trouble. And while they're in the driving seat and it's their extreme misogyny (apparently rooted in jealousy, as they despise the women they want to be but never can be) that is dictating policy, I want the entire boiling of them shut out from all women's spaces, lock the door, set the bolts and get the boiling oil ready.
