So some guy minding his own business, sitting in a restaurant eating a cheeseburger is to be seen as no different than say, Jerry Sandusky.
When reality intrudes on their fantasies, as when jobs don't just fall out of the sky, when our enemies don't suddenly change their mind after we've bowed to them, or when the Obamacare implosion accelerates, they aren't able to re-examine their premise, they ignore it, blame others, throw more money at it, and lie.
And occasionally, their global warming research vessel ends up stuck in the ice. Why all that ice is there, and what it says about all their computer models, is ignored, They simply pretend it didn't happen. Anybody who tries to point it out is decried as a "climate denier", whatever that means. The left is convinced that anything you think or say that contradicts them is simply proof that you're wrong, or a racist, or something.
When you're a True Believer, you never need to examine your thoughts about anything.
