We're also to some extent innately combative creatures. People will say "Oh, I showed people the facts and they still didn't change their mind. They're just idiots stuck in their ways." Okay, cool. When you tried to present these facts, did you do it in such a way as to treat them courteously or as an equal, or did you do it in such a way that you got to feel like you were dunking on them rhetorically? Because it's not as simple as presenting someone with facts. It's doing so in a way that doesn't make it feel like you're trying to establish some kind of superiority over them. Because then they're not presenting facts to you, they're just attacking you and your position. And these are very different things, conceptually and emotionally.
