You've bought a leftist lie. Religion helps win war, it doesn't start them. War starts from envy which is caused by vanity/pride. Germany didn't start WWII over religion, but because they envied their neighbors land, and they envied the Jews success. Germany is a hotspot of envy. The German language has special words to describe many forms of it, for example Gluckschmerz, unhappiness at others success, and Schadenfreude, happiness at others failure. Neidkopf, envy heads over front doors, are architectural faces meant to scare away envy and the evil it brings.
The sand simians didn't fly our airliners into the World Trade Center out of religion. They did it out of envy over America's power and success, and a Muslim inferiority complex. It's no accident that they since built the world's tallest skyscraper after knocking ours down.
Leftists are driven by envy, so it's not surprising that they are quick to blame something other than envy for destruction, murder, war, and voting Democrat.
