That's an insulting way to describe Religion.
The Left has a secular worldview. It is at variance with reality. I agree with much the author says, and I think the devil is behind the whole thing, but I don't think Leftism is really a religion.
IMHO...Religion requires faith, without which many of the precepts that form the foundation of belief can not be proved. Without the faith, one might question things that the faithful might not be able to answer convincingly. Faith in God isn't debunk-able as, say AGW is. Atheists can not prove (to anyone but themselves) God does not exist, and believers can't prove to them He does. Stalemate. Faith bridges the gap, a bridge usually built by some life changing event.
Liberalism is religion the way Greek Mythology was religion. Logic and common sense can pretty much destroy it, but liberals are emotionally invested such that logic and common sense do not penetrate. Their emotion epitomize the term blind faith. In leftism, unquestioning faith is required or it falls apart. And liberals, within their means, are every bit as nasty to the unfaithful as are Muslim jihadists. The more excellent the counter argument, the more bile generated in the ranks of the faithful towards the bearer of truth, which is why liberal atheists are so nasty in their aims and disposition towards Christians. Liberalism is an ungrounded religion, which is why liberals are so angry and unhappy.
Yes it is, with articles of faith that can’t be questioned.
