Every thread on Reddit even tacitly linked to matters of faith bears host to a circle jerk of these pricks. First it's "Religion is the scourge of humanity," like they think they can just address every idea men have had about the metaphysical with one sweeping comment. Then, if you press them for an example, you get, "The Bible is old, God didn't actually write it and I think some of the characters were made up!" Because every religiously devout person believes in the divine origin of the Christian Bible.
Fuck ratheists. They peddle their simpleton rhetoric to budding young minds who could otherwise benefit from healthy and constructive questioning of their beliefs.
