He didn't mention endorsing the transwoman Alexis, whom he knows and who has passed the bar to compete in the specific pageant he signed up for. Instead, he's mentioning this teen (whom he shouldn't know) and Charlotte, who he's been following around on Twitter. He always starts talking to her, never the other way around, and under the surface friendliness you can tell Char's nervous and trying to extricate herself--while he keeps insinuating that to support LGBTQ rights, you have to support him. She has that female socialization effect where she's reluctant to tell someone being "nice" to her for their reasons to fuck off.

@wabbits, it's actually four pageants;
1) Ontario Galaxy told him he couldn't compete in their nationals b/c if he won, the internationals wouldn't accept him for being trans. He's filing a complaint against them;
2) Beauties of 5 Continents, which DOES have a irl address in Vancouver and local phone number but reportedly screens by phone (unknown from where) and has the pageant activity taking place on a Caribbean cruise ship. Apparently someone told him they only accept real women. He's filing a complaint against them;
3) Miss BC, from which he was eliminated/dropped out. He's said he's not filing a complaint against them;
4) Miss Perfect Woman and Model Search out of Florida, says he has paid to participate. This is the one that makes candidates buy 1970s spandex jumpsuits to compete in. He'll probably make them buy him a dress as theirs are too small. If they don't, he'll go into a narcissistic rage to try to complain about them. If he is in FL by then, he'll probably drive out to where Null's po box is to stage another Saxenda overdose to raise awareness about hate.
