It's a fair question and the answer is as multi-faceted as it is insidious. In order to be a tranny you have to be gullible, socially isolated and susceptible to suggestion (and autistic to some degree, naturally). The very second someone makes even the slightest mention that they're contemplating what life is like as the other sex (a perfectly natural thing to be curious about), the groomers pounce and start feeding the victim BS about how they should explore that curiosity further because they might just be trans.
All true. It's also important to remember that trannies lie, frequently, and that the truth of these procedures is heavily censored, especially on Reddit. Trannies lie about these procedures and many of them operate under the delusion that the surgery will give them a true and honest vagina, instead of a mutilated outside-in dick only capable of feeling pain, if you have any nerve endings left to feel anything at all. Pooners believe they will get the massive porn-star cock of their dreams and not a gross, stitched-up fleshy coke can sewn to their crotch that is prone to infection and has no functional purpose whatsoever.
Then you might ask yourself "well, once they realize how awful it is, why don't they try to warn others? Why don't they detransition?" The answer to this is the sunk cost fallacy. These people, having gotten the surgeries, have most likely cut off all of their "transphobic" and unsupportive friends and family completely at this point. They have nobody left who will accept them except the tranny hugbox, and the tranny hugbox doesn't like dissenters. They
could try to cut their losses, lose all of their hugbox friends, and crawl back to their former friends begging for forgiveness and admitting they were wrong the entire time, but that's extremely difficult even for normal people to do. It's hard enough for a normal person to admit they fucked up, even with minor things. How much harder is it to admit you royally fucked up? To admit that you so catastrophically, fundamentally fucked up that you basically ruined your entire life? Even if you do try to make amends, there's no guarantee they'll accept you back, considering the disgustingly awful way trannies tend to treat their unsupportive, "transphobic" friends.
I almost can't blame them for not going that route, because it's so objectively horrible in every way. They've trapped themselves in a scenario where there are no winning moves, just varying levels of despair and misery, so they pick the option that would provide the least suffering, which is desperately clinging to the delusion and hoping that someday, eventually, if the planets align, their choices will be right and they'll be vindicated. It's their only salvation at that point. You see in this and the SRS thread the trannies insist that, eventually, it'll all work out. Just one more revision, just a few more estrogen pills, just a few more T-shots, and it'll all be worth it, right? It's the sunk cost fallacy on full display; they've already given up so much, there's no other path forward but to keep laboring under the delusion that, eventually, all of the sacrifices they've made will be worth it.
It never happens, though, and we all know this. This is why the suicide rates are so staggeringly high for trannies. Eventually, they realize just how badly they've fucked up, and how they can't fix any of it. They realize they threw their whole life away for a lie. Nothing left to do at that point except take yourself out.
Trannies are playing a game of poker, with their lives as the bets. They're down to their last few chips, all that they have left, and their opponent has just raised. They can't match the raise, and they have an objectively shitty hand with no viable cards, so they can either fold and try to keep whatever scraps they have left, or go all in, hoping and praying to whatever deity they believe in that their opponent is bluffing and they'll win the pot.
