Breitbart out-Acorned Acorn

Victor Davis Hanson writes about the late Andrew Breitbart, RIP.  I was trying to explain to a friend what was significant about Andrew Breitbart.   I think this column by VDH nails his significance, especially this:

In other words, he out-ACORNed ACORN, and that, I think, spurred most of the venom against him: It was not just that he had countered the message of the Left, but he often humiliated it by employing its own tactics in a way that made himself either safe from their criticism or the critics of his technique abject hypocrites.
Under the old “truth to power” orthodoxy, considerations of race, class, and gender supposedly excused the boisterous conduct and occasional crass invective of the Al Sharpton, Michael Moore, Code Pink, or Cindy Sheehan sort. Breitbart demolished that exemption, and more or less warned that he could employ the same sort of agitation as the Left, but to endorse and enhance the ideals of a free-market and individual liberty, and he dared his opponents to reject his methods on grounds that they were somehow crude or unfair.
