You're right. Though simple lists of anecdotes and examples do nothing because they are essentially infinite - you could list one thousand evil deeds on either side and still be cherry-picking, or be listing things that the other person simply disagrees with subjectively even if you both agree on the factual parts, and that's not even considering the cases where you each disagree on the facts. But you're right in that if the perception of how badly one "side" behaves vs the other is almost perfectly opposite between two people (sounds like "party A is shitty but human, party B is evil"), they might as well be aliens to each other. You can't resolve differences in reality.
