“How can anyone not know this?”

I forget who said something to the effect: “The biggest problem is not ignorance, it’s what people know that isn’t true.” There’s many people in the world—especially in academia—who “know” what you claim is wrong. Don’t ask them to prove this with evidence or even argue it intelligently: propositions that are the exact opposite of the ones you state too often are a shared assumption in many circles.

You can’t expect critical thinking from individuals who can’t or won’t think critically!

Thanks DrC! People today in the politicized Groves of Academe are mostly amazing in their malevolence, arrogance, ignorance, and lack of true education. Harvard has just one libertarian professor in the whole school, evidently. Such is today's post-modernist Dark Age era.

I think your quote comes from Mark Twain: "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so."
