While I think Maher has some good things to say, religion isn't the sole cause of these things, as proven by some of the members of Agnostic.com and the state of civil liberties in China and N. Korea. Religion is the cause of much that is bad but not the sole cause.
Religion was a need that evolved for the curious and imagining. Pre-science - it answered lots of questions. But by the Middle Ages....as science dawned -astronomy, then microbiology began to poke big holes in the story of creation. Then it was too late; the Crusades, the inquisitions all worked to force people to think religiously or perish. We're coming out of that slowly; too slowly for me and most scientists...but we are evolving;
But we are running out of time; We are headed towards extinction;
