Religion also caused most tribal warfare, so it’s a wash at best.
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.
