> You genuinely think the type of people who subscribe to subreddits like coontown and fatpeoplehate are going to have their mind changed by people on the internet?
Yes, because I've personally met such people.
> I've had no success changing the minds of people who think that being trans is a mental illness despite citing numerous peer reviewed articles. Maybe I'm going about it wrong, but I'm not sure it gets more clear than pointing to a bunch of scientists that directly contradict their understanding.
Changing minds takes a lot of empathy and skill (and usually time) to pull off consistently in person, much less online; I'm not surprised that a strategy of throwing scientific articles in people's faces (which they will probably never read) would be unsuccessful. Regardless, even if you are successful, you will probably never know unless you have a long term relationship with the individual.
