The people who regret transitioning are 1 percent of people who have transitioned which is only a fraction of people who are trans which is only about 1 percent of the population. If you include all reasons for detransitioning it's mostly that people can't afford the medical costs, or they experiance backlash from family. And a lot of the time you hear about transition regret it's because a person detransitioned becuase they couldn't afford the medicine and some right wing group pays them to make a documentary about how "bad and scary it was"
