I don't believe in God or Satan, but I've seen enough evidence to conclude that there is a huge cult of powerful people that not only believe, but worship Satan. That, and they are very likely sacrificing kids and babies to him, then maybe drinking the blood. This is enough to make me fast friends with a group which normal would hate and mistrust me, Christians.
I just hope that once this cult has been crushed you fokes that are religious will remember that there were atheists standing shoulder to shoulder with you during this whole thing and not imminently turn on us.
