Meanwhile, the religious nuts just quote random bible verses, and are for the most part ignorant to any other viewpoint but their own."We have to prepare ourselves with an intellectual defense, so that way, if we're approached by family, friends or co-workers who find out we're atheist or agnostic, we can stick up for ourselves," he said.
For all intents and purposes, my religion is common sense.
