I wonder, do they get mad about men that got higher pitched voices? Or do they try grooming em? I've weirdly never seen troons on the naturally high pitched male side now that I think about it, it's kind of weird.
I have a completely bullshit theory with no evidence beyond casual observation and personal experience, but I think it has to do with masculine security and how much challenge they've faced to their masculinity.
Men who are naturally less traditionally the superficial ideal of masculine (lither builds, more narrow shoulders, weaker jawlines, high pitch voice, shorter, whose genetics lean towards less bulky muscle, less prominent chins, etc) have to naturally grow up with more questioning and securing themselves in their own masculinity. Some try over compensating, but I think most just learn to get over it and realize that being a man doesn't require a perfect score. This makes them more resilient to tiny things that don't match certain traditional masculine stereotypes with themselves preventing a full meltdown of sense of self compared to those who are superficially closer to the masculine ideal naturally who just don't need to get through those struggles as often.
So a guy with a high voice, who is naturally lithe, and a bit short is actually more likely to handle something like discovering he likes having soft skin and being able to reconcile that with his masculine identity than someone who has never had to regularly reconcile their masculine identity before. "I'm still a man despite having a high voice. Therefore I'm still a man even if I like soft skin" versus "Oh God I like soft skin, but that isn't manly! Therefore I must be a woman!"
You can see it in how they talk. Statements like "If you ever questioned your gender, then you're trans" or "if you ever had feminine interests, then you're trans". It's clear these people never contemplated their masculinity and developed an internal belief of what was masculine beyond "someone who isn't feminine" and, despite their overt masculinity in most superficial and deeper levels, they obsess over that one feminine detail until they suffer enough of a ego breakdown and decide they must be a woman.
