The Birth of a Known Fact

Via Redstate:

Known Facts™, as you may well know, are things which are not really facts at all, but are clung to by the left with all the force and tenacity of runaway religious fervor. It is common for conservatives to express amazement at how liberals come to believe in ridiculous things like War-for-Halliburton, and even more, to simply assume that the rest of the world shares in their delusion. If you ever ask a liberal to provide you with evidence for one of these bizarre conspiracy theories, they will likely respond in amazment, "Everyone knows that - it's a Known Fact™ that (Bush lied, we went to Iraq for oil, or whatever the liberal conspiracy theory du jour might happen to be). It's less often analyzed how these Known Facts™ come to be, but the recent bru-ha-ha over the NSA wiretaps is slowly but surely giving birth to another Known Fact™ - namely, the Known Fact™ that Bush broke the law by authorizing these NSA wiretaps. We are therefore provided with a unique opportunity to study the phenomenon as it occurs.

The whole study is worth the read.
