Teaching not to hate is hard to do. Instead, teach everybody is different, and that that is normal. Teach them that people have different looks, different backgrounds, different religions, different believes and personal convictions, and that that is normal. Expose kids to those differences, so they won't see different people as Other.

Don't make it an us-vs-them thing, but unite them. Let them embrace those differences.

Differences will be ranked, and they will be used to form teams.

You can't stop human nature. At best, you can divert it to something less problematic, like nationalism. If everybody is on Team USA, then there is no room for racism.

We will never eliminate the urge to judge, rank, and exclude. It's very deeply in our DNA. All the social mammals have the urge.
