I actually don’t think kids are more accepting of other people than adults. Kids and especially teenagers are not accepting if you’re even a tiny bit different than them. It’s mostly because we’re immature. Adults are extremely accepting in my experience.
in some ways, yes. but kids haven’t been trained to be as discriminatory or to treat some people differently (if you’re a minority or from a marginalized community, then you’d know)
also, when kids are mean, it’s usually more forgivable, since they usually aren’t trying to be mean or make you feel bad.
