One of my cousins (age 23), at the end of weeks-long stay at an inpatient psychiatric facility, came out as trans to his parents. They are very supportive, if a bit surprised.

I want to help them and my cousin out and link them to some online forums/discussion spaces. He’s (AMAB, hasn’t mentioned what the new pronouns are) very online, so I’d be most interested in stuff for him. I know some of the sites don’t have the best reputation, or are very polarizing, so I’d like sites that are positive and supportive.
