Why can't we just be "excellent" to each other?

Maybe for self-important, judgmental, confrontational, and closed-minded types. I could see the conversation going something like this:

You: I don't believe in your principles.
Me: You don't have to. Use your own brain to decide what is right for you. Good day!
(Technically, the discussion could end here, but some may want an argument.)
You: Don't walk away! I want to do things that go against your principles.
Me: Ok, you have me curious, such as?
You: Like dumping used motor oil in a creek, spitting on the homeless, and not giving away a penny to charity.
Me: I ask you to re-evaluate your intentions, and decide for yourself if they are good or bad.
You: I've already decided they are good, and am going to do those all tomorrow.
Me: Ok, sounds like a busy day! Just so you know, we have laws that cover the first two, so you may get into trouble there.
You: I'll take my chances. It is right in my mind.
Me: And nobody has a gun to your head, so charity is voluntary, so that's your call.

We're never all just going to be excellent to each other with that pitch.

Modern humans have  been around for maybe 200,000 years and have fought and killed each other from the beginning.  Obviously we can't be "excellent" to each other or else we're slow learners.
