Harlan's Razor leads us right back to the issue I spoke about before, which is the tendency for gamers to seriously overestimate the stupidity of people they disagree with. The sentiment he is expressing feels good. But I don't think it leads to greater understanding. That doesn't mean people having uninformed opinions can't be an issue. But I think it does mean, thinking you are smarter than the other person in a disagreement because they are less informed, less educated, etc doesn't entitle you to be a jerk.
