Not this

I don't know. I think the answer is simple at an individual/family/community level (basically just taking a genuine and supportive interest in whatever hobbies kids pick up) but elusive at the societal level. In general I'm very anti-propaganda, so that biases me. By the way, I hope you'll post this to s/GenderCritical too.

Edit: more thoughts: I think one of the most important things we can do is promote resilience. There's no getting rid of the sense of otherness felt by people who fall outside the center region of a normal distribution, but we can make an effort to return to a "sticks and stones" mentality. And this can be done sensitively, by sympathizing with kids when they're sad and letting them have that process, but also letting them know that they will be okay and that they might even be tougher when all is said and done. I also think it's important to get kids thinking about their ethics; in the case of a GNC kid, encouraging them to question whether their nonconformity actually hurts anybody, for example.

Also I fixed the link - thank you for letting me know!
