Great challenge.
1. Individual > Group
We're being taught to see people as part of a group BLM, LGBT, white privilege, Christian, Ukrainian, Israeli, maga etc. And when we see them as a group member, rather than an individual it's very easy to hate.
You're group think's X therefore... just because the majority of the group are this way doesn't mean I am. We all disagree with our in-groups on many points.
When we view people as individuals it's much harder to hate. Sure you can still hate, but hating 1 person rather than a million members of a group is great progress.
Next time you notice your judging an average of a group instead of the individual Infront of you take a step back and reassess what you're doing.
