You are quite correct. The only way to any kind of positive resolution is to find out what one has in common with other people, and work from that point forward towards some kind of mutual understanding.

If you take the time to listen to what people say you usually discover that like you, they want freedom, justice, fairness, peace, and all those other good things. They want truth. They want everyone to be safe and have a good life.

But they lose their good judgement when they start arguing and stop listening, and when they turn someone else into a stereotyical symbol for everything they think is wrong in the world.
