Compare this to troons who dont necessarily experience anything similar, they just want big tits like in bimbo sissy hypno porn.
Oh, no, Chris is absolutely an autogynephile. I remember something like a two year period where half the videos consisted of Chris dancing around rubbing his moobs while begging for money. He put vibrators in his bra, and listened to autohypnosis/subliminal frequency videos about inducing breast growth and lactation, including preposterous claims like "for two months my breasts have grown one inch forward per week". He's perverted even by troon standards.
The traditional approach to defining who is a genuine tranny or not was the people who had such severe symptoms of gender dysphoria and were clearly pathologically disgusted at their own genitalia, to the point that they could barely function as a person.
Chris’s inability to function as a person is not related to his genitals in that way.
I just buy that he really doesn't like being a man. In the golden age that was disguised by his impressionable nature; he lived with Bob, who was quite conservative, so Chris would turn his "men are horrible" into "gays are horrible, I'm STRAIGHT, get it through your DANG DIRTY SKULLS", because he thought Bob would be disappointed to have a faggot son. Chris is autistic, he doesn't deal well with change, and puberty is a huge change, it's natural that he hated turning from a cute kid into a pathetic incel teenager.
You can use whichever definition of "who is a transgender" you want, but there are effectively two modern camps ("anyone who says they are" and "someone who gets a diagnosis and is in transition with the end goal of genital mutilation with a remotely plausible claim that it's not just a fetish"), insisting to stick with an old definition neither camp agrees with will only settle the debate in your own head. I'm in the latter camp, and think Chris does fit the definition about as well as someone so intellectually disabled could. The sticking point is whether he wants the mutilation or not (or rather, if you can count religious faith). Chris clearly wishes he had been born a woman, and a big part of the Merge is that he will finally be a real woman, by moving to a world where magic is real. He prays for, and believes that, he will one day become a real woman, rather than just a man who gets off on public humiliation.
Even if you don't count his religious beliefs as expression of a sincere wish, Chris has several times made statements to the effect that "if I can't grow ovaries and a womb naturally, I will get the surgery" (but then again he has also made claims like "I'll never get it chopped off"). The hangup is probably his desperate desire to father children, ie he won't have the dick chopped off only because whatever shred of reason remains with him screams that it's just castration.
