This is true but in fairness I don't believe it's a uniquely religous problem. Humans are by nature huge jerks that hate anyone who isn't themself. Religion, non-religion, politics, sports, anything. We never really grow out of the beat-up-the-kid-who-looks-different mentality on the playground. Some people are cool and layed back about life. Others are jerks that judge others by how simliar they are to themselves. If we all disagree on everything else let's all agree we hate the jerks who fear difference of opinion.
