That's a tough one, and it def wouldn't work on everyone, but some of it is better than nothing. When I was in middle school, some of my classes had a big focus on "tolerance" of people in different walks of life than you. Honestly, tolerating people is the bare minimum we can ask. We don't have to force endorsement or anything like that.. Just help people think from others' perspective, take a walk in their shoes.

A total lack of this has really fucked us
