'At a festival called Peacestock in Wisconsin last weekend, I met a woman who lives in Little Falls, Minnesota. That city had forced her to take down signs in her own yard, signs that said "Occupy Wall Street," "Back the 99 Percent" and "Boycott Monsanto." But Robin Hensel noticed that the city itself was displaying, in violation of the same ordinance, a banner reading "We Support Our Troops."

For anyone who's been visiting outerspace for the past half-century, "support our troops" is, of course, a phrase meaning "support whatever wars our government engages in." Thus, we ocassionally see signs reading "Support our troops: Bring them home," a message that is understood to reverse the common meaning of "support our troops" by giving it a literal interpretation.

Well, Hensel proposed that the banner come down, in compliance with the law -- acting on the idea that even bad laws should be enforced fairly. And then came the death threats.'
