These are why the SOC exist. Charles Kane is a perfect example of that. For the protection of all true trans people, you must ensure that people with significant mental issues or things clouding their judgement aren't allowed to transition, de-transition and de-legitimatize their right to be who they are. I'm all for people being thorough and tough, otherwise you'll get a situation where people end up badmouthing, falsely representing the community (less than 0.01% of women who fully transition, transition back) sueing, and then the requirements for transitioning end up being completely over-the-top, ruining it for everyone.
