All religions are a threat to humanity. Islam is currently the greatest threat, but Christianity is not far behind. In the age of nuclear/biological/chemical weapons that can wipe out countries, it is only a matter of time before such weapons are used on a massive scale to kill millions of non-believers in the name of someone’s god. Unless someone invents a pill or surgical procedure that cures people of religious belief and forces it upon the masses, we’re all doomed (just the way the religious people like it, not so ironically).
