They get terrified by "secular humanism" or "Godless atheists" because pretty much the only exposure to such things has been from socialists, communists, and suchlike. Hell, how do you think the destroyers of the United States were able to hoodwink people into putting "Under god" in the pledge of allegiance, in the first place? The sales-pitch was to make us different from the "Godless Commies". In the popular mind (controlled and shaped as it is by the "activists" and their social agendas), the concepts of Communism and Atheism were skillfully and secretly blended, so that the Common man can no longer tell one from the other.
Yep...It was a conspiracy to keep atheists down under the boot of militant Christians... *sigh*.
No, the fear of atheistic society is brought on by people like Mao, Stalin, Saddam and Hitler who, at the time of their power, were viewed simply as powerful atheists like this guy considers himself to be.
There is some crappy religious leaders out there. I have no doubts about that. But one of the major foundations of Christianity is that man is not perfect. Expecting that from anyone who claims Jesus as their savior is wrong and is either too ego-centric to figure it out, or plain ignorant about the subject.
Hitler? AFAIK, he was a theist all his life.
