Re: You didn't ask a question. You ventured an opinion.
This is where Gingrich got that idea. Gingrich even credited the author back in 2010.
It is indeed the nature of opinion that it cannot be proven. It is intellectually effortless, requiring not only no proof, but no thought, no internal consistency, no scholarship, no reason. The attractiveness of opinions is that they're immune to argument. Nothing wrong with opinions, in and of themselves, but they're a hell of a way to make important decisions.
Incidentally, the liberal assumption that their opposition is a load of "Neanderthals" is a dangerous one, especially when the twin engines that power their own party are stupidity and ignorance.
