What troubles you more, religious fundamentalists / extremists or atheists?
Who says atheists are never religious fundamentalists/extremists? I’ve certainly known a few who qualify. Tha Marxist and Maoist mass-murdering revolutionaries certainly did. But fundamentalists aren’t the same thing as extremists, though there are certainly some extremist fundamentalists – primarily within Wahibism. But I don’t know anyone who’d classify the Amish as extremists. In my own life, “religious fundamentalists” are at worst a minor irritant. I’ve had no actual contact with an actual extremist – except arguably of the Left Wing atheistic variety: but such are the hazzards of working in the PC gulags that are the modern academy. Not all atheists, but the smug obnoxious dimwitted arrogant ones have certainly been the most offensive and annoying.
