I can't say that I blame you and other posters here too much for being turned off of religion in general and christians in particular. You are right about people doing some pretty wicked things to other people throughout history in the name of God. And imo nobody should deny this or minimize the significance of it. Obviously whether or not one believes in God at all adds another troublesome layer here to what is going on with influential Evangelicals in politics.
To this I would say what others have. Everyone, christian and atheist alike have equal rights under the law and the freedom to participate in the democratic process. I also regret to hear that people reject God altogether based on the actions of extremists. It's a mistake to paint all with the same brush.
