I remember reading the Song of Roland in high school. It's a fairly famous, old Christian epic poem from the 11th century. In it, I remember it depicted a Christian knight and an Islamic paladin with diametically and fundamentally opposed views (this was written in the middle of the Crusades) sitting down and sharing a civilized meal together and having a conversation. This is what a civilized dispute looks like. Later they might have fought each other to the death for their religion, but they were still capable of reason and civility. Note that both Christian and Islamic sides were accusing each other at the time of cruel atrocities - and yet the Christian ideal of tolerance includes the possibility of civility with everyone, regardless of what the sides think of each other.
