Neil Mammen is a wingnut and author of the elegantly titled Jesus is involved in politics!: Why aren’t you? Why isn’t your church? The Only Way to a Happier, Healthier, Safer and Mutually Prosperous America and 40 Days Toward a More Godly Nation: Why Only Churches Can Lead Us to a Happier, Healthier, Safer and Mutually Prosperous America (both published by the hate group the American Family Association).Mammen is the kind of guy who thinks people with political power ought to be religious fundamentalists, and is very concerned about politicians he perceives not to be true Christians™, such as Obama (so, the definition of “true Christian” is someone who agrees with Mammen on politics, in which case it follows by definition that only true Christians can govern the way Mammen would like): “… anytime you get somebody who disdains law [like Obama], doesn’t care for the law, who hates the Lawgiver and doesn’t think he deserves his sceptre, doesn’t think that the law giver knows what’s good for you, for us, then naturally you’re going to get pain, suffering, disease and death.” Note that, according to Mammen, only Christianity™ is based on reason and rationality; all other religions are based on faith.
He has also written about how to protect your kids in college, where they may be exposed to facts that contradict what their pastors taught them and discover that people of different faiths and political convictions aren’t necessary pawns of Satan.
Diagnosis: Wingnut fundie; not one of the central characters in the crazy movement, but probably not anyone you should listen to nonetheless.
