Have you ever sat and watched the leftists carefully? Not so much to hear what they say, but to watch their body language. Most of them read like an open book. I've seen the postures and gestures that signify lying, evading, fear, loathing, disdain, fury, hatred. Sometimes all these will show in one individual in the course of a rant, harangue, or protest.
I once watched a former-churchgoer-turned-atheism-activist give a lecture as a rebuttal to "life after death" proponents. The thing that struck me most wasn't her speech or manner: it was what I saw in her eyes. I saw straight in, as it were, to a bottomless terror. This woman's atheism was driven by a deep fear! Of what? That she was wrong? That life DOES go on eternally? Why else was she so frightened? Of course her voice was most strident and her views most obvious. But there underneath, was her inner self crying out.
