I'm not sure actually. It boils up because people engage in debate instead of doing two things: * Taking issues to a vote. * Respecting boundaries of other people. Debate implies you can change other person's opinion. However, it often tries to talk your way to measures that would never float in a fair voting, or that violate already existing personal or property boundaries. After a few rounds of debate you're supposed to take it to poll booth. Instead it often turns into name-calling and shouting "nazi" at each other. That kind of discussion should be avoided.
