The general consensus I've seen with Troons is that they want to convince others and themselves that what they're doing to themselves is really wholesome and cute. The "modern day online transgender girl" wants one thing and one thing only: To turn themselves into an anime girl. For example, they try way too hard to present themselves as female online, using not only female pronouns and bright pastel colors in their profile pictures, banners, and, quite often, their drawings, but also by talking in "Katy teh penguin of d00m" speak, or stuff like that.
The more they can convince people to validate them, the more they can convince themselves and others to look away from all the ugly truths that come with doing grotesque things to their bodies and minds. And so, you get people who in any other world would be politically neutral being strong-armed into saying troons are wholesome, have them treat them as they would any other cute girls in real life, or online, calling them "girly pops" or "oomfies."
I've also seen plenty of people bring up that another reason people commit themselves to trooning out is the lack of a GF, or the "incel to troon pipeline". They never got to have a cute goth or scene GF, and so they try to transform into one to compensate, as thanks to radical 3rd wave feminism, a lot of women abandoned things that made girls "girls". So, now, whenever I'm online, there seems to be this "threadhold" where if a girl online is trying
way too hard to be girly, using girly colors like pink or saturated colors, posts pictures of cute characters, looks and acts like a happy-go-lucky girl you would know in Elementary school or Junior High, I have no choice but to assume the person lurking behind that username is someone who's currently ODing on HRT pills.
Where Bridget comes in is that people see him as an unofficially-official mascot for this movement. ArcSys made him with the intent of having a cute character that was a boy instead of a girl, except the long-term effects of this would lead to a lot of problems. For one, like I said, trans girls
love cute characters. They want to see themselves as a cute anime girl, or use cute imagery in their online profile or works. Bridget is cute, he stuck out from the other members of the GG cast through things like his design and the "Everybody is gay for Bridget" meme.
Another thing to keep in mind is that the modern day FGC is very meme-driven. For example, early on in Strive's life, May became a meme thanks to her being annoying to play against. "Totsugeki!" became the go-to meme for Strive, and would cement May as a bonafide Twitter meme that summer. Even people who barely play GG, or know jack-all about it, know May.
Because Twitter, especially in the wake of Covid, suffers heavily from brainrot across the board, people turn into monkeys whenever they see a cute character that lines up perfectly with the worldview they want to push. I could write so much more about why Twitter ate up Bridget in the way they did, and the psychology behind their (I'm just gonna call it what it is) lust for trans "representation" in the wake of progressivism taking over the Internet after #LoveWins, but that's best saved for another day.
Bridget is legit one of the few ficitional characters who actually deserves his own KF thread.
