There are reasons to feel ambivalent about his style of activism, but Andrew Breitbart earned the affection and gratitude of many conservatives for giving bullies on the Left a taste of their own medicine.

Of course, standing up to bullies in the world of science is among the main things we do at the Center for Science & Culture, and so we can only recall with admiration his success in the fields where he chose to ply his trade, indicated by the names of his news sites: BigHollywood, BigGovernment, BigJournalism, BigPeace. If we had had his ear we would have suggested an additional site, no less important than the others: BigScience.

If a man is known by the enemies and by the friends he keeps, Breitbart must be judged to have lived a good if tragically short life. RIP.
