The research is also highly motivated. A researcher who found that sex change operations were harmful would be targeted for endless harassment by gender activists, if they could get published at all.
A researcher who found this would be feted by the conservative/evangelical wing of the US political spectrum. They would stand to make a ton of money in the book and personal appearance circuit.
The fact that people can decide they’re not trans is not particularly material. This is very uncommon.
The conspiracy that such research must be politically motivated is a contrived argument and also falsely paints a dichotomy of saying that it must either help or harm. My assumption before doing the research was that they would find no effect.
You really lost us with this.
Many, MANY people dally with the idea of being trans and decide it's not for them. This is extremely common, and is probably the overwhelming majority outcome for all people who are ever trans-curious.
Show your research please.
