Someone should tell liberals that the old days are over. Not so long ago, if you wanted to prove that a member of the chattering classes had flatly contradicted himself in order to advance a political agenda, you had to go to the library, get a roll of microfilm, insert it into a machine, and then search for the earlier statement. If your memory was faulty as to where or when the earlier statement had appeared, this process could take hours, even days. Often it wasn’t worth the bother.

Today you need only click the icons for Google and/or YouTube, push a few keys, and bam! — you have proof positive of the chatterers’ shameless hypocrisy. A few more clicks and their intellectual perfidy is all over the Internet.

The recent spate of liberals decrying the hostile rhetoric of the right following the tragedy in Tucson is a case in point. One would think that the incivility had started on January 20, 2009, and that political conversation of the previous eight years had been a modern-day Socratic dialogue. As Michelle Malkin demonstrates — in spades! — that is not exactly the case.

I don’t know how long it took Michelle to come up with her list, but I bet it was less time than she would have needed to take the bus to the library.
