I think trooning out is a way for many to leave an old unwanted identity behind, reinventing themselves in a way that's easier to address their actual problems that makes them unhappy with who they were and where they get support from people just as fucked as them. This is also why "silently turning into a woman" doesn't cut it for them, everyone *must* know and also most of all - be supportive. If you pay attention, there's always an unhappy life beforehand that can be easier explained with other things than "wanting to be a woman all along". I don't know about you but if I had the wish to be recognized as the other gender, I'd strike everything that'd make me stand out as actually-not-a-woman, which would include all these ""trannyisms". The genuinely fucked thing is that it's easier to troon out than to actually get support for legitimate mental problems. I blame the lack of good mental healthcare and the social stigma attached to getting help. (that isn't hormone therapy)
You're spot on for some troons, I've known a few troons who've made poor life choices or worse, broke the law and want to escape their past without owning up to it. Other times their life is filled with trauma and abuse, and their coping mechanism is to troon out and be a different person entirely.
On the other hand, with other troons I've had interactions with its not solely about wanting to leave the old identity behind (though it does play a part). There's a strong fetishism aspect to trooning, and with people like Foxworth they're doing it because they fetishize the idea of taking pills to turn into a female. With furries this aspect will manifest itself in some furry who roleplays as a female character online wanting to be a female as well. With weebs, they'll go from wanting to fuck anime girls to wanting to be the anime girl they could never fuck, or wanting to be an IRL trap.
Then they'll show off to everyone around them that "I'm trans uwu," especially in fetish and sex related corners of the internet. Trannies also tend to get a bad rep for showing off their girldicks and neovaginas, especially when they do it on NSFW chatrooms/websites that tend to be for males/females only, or on dating apps when they lie about their sex. Then when they get rejected from said groups, they'll throw a giant tantrum and write thinkpieces whining about how they're not dating straight people/lesbos and how everyone is a bigot. Hell look at Phil, he shows off his stink ditch all the time, or the horny ladyboys/traps who live their lives as sex objects.
That last part about how it's easier to troon out than to get support I agree with 100%. I've noticed a lot of trannies were mentally ill to begin with, and instead of getting help for their condition they'll decide to troon out thanks to bad influences. There are websites and people out there that actually tell you that if you're feeling down and you played with girl toys as a kid, you're actually an "egg" waiting to be "hatched" into a transgirl. Then they start HRT and their mental illnesses rear their head even uglier than they did before. I've known trannies who have mental issues including one who was a drug addict, and one who I saw start HRT and a year or so into it was being arrested for fighting with his MtF girlfriend (after posting a ton of "i'm depressed uwu" tier posts).
With all these people, they're guaranteed to get a bunch of new tranny friends as well as well as a support group which tries to be "validating" and "accepting" by being ass patters who blame issues on being a transgirl/the transphobic world and only rarely telling people that they're the problem. Plus, with being trans being the new fad, many broken people don't think twice.
But either way, when you boil it down it all comes down to "I don't want to be myself, I want to be something I'm not and can never be", mixed with what people feared would happen when headmates were all over Tumblr.
