There are cases of people desperate to have their 'rogue' leg or arm amputated. Generally, when surgeons have amputated these people feel better afterwards.
Larry, would you say this meant that these people were right, that the arm or leg didn't really belong to them, and that God/nature made a mistake and they should have been born without it? Or would you see the amputation as an attempt to alleviate the suffering of a person with a clearly very complex mental illness?
I don't think anyone here would say that dysphoria doesn't exist, or that an adult shouldn't have hormones or surgery if it would make their life better. Just that it still doesn't make them literally the opposite sex, because that's biologically impossible. These people, however, are known as 'truscum' to trans activists.
People with no dysphoria, who make no effort to physically transition, just say they're the opposite sex because of some undefinable gendered feeling, and believe that children as young as three who show preferences outside of culturally-defined gender stereotypes must be trans, though? Not the same thing.
