views to David Duke's racism. He has also reviewed popular economics books Freakonomics and The Undercover Economist for the Wall Street Journal. Landsburg has spoken at many distinguished events and in February 2012 he spoke at Warwick Economics Summit and the Adam Smith Institute in the United Kingdom. In March 2012, Landsburg supported some of pop radio personality Rush Limbaugh's attacks against a Georgetown University student, Sandra Fluke Fluke spoke before Congress advocating mandating birth control coverage in some insurance programs, citing their use in preventing ovarian cysts. "There are really good arguments for subsidizing and bad arguments for subsidizing [birth control]," Landsburg said during an interview with WHAM-TV. "However, [Fluke] didn't bother to make any. She made no argument. She simply said she wanted it subsidized." On his blog, Landsburg discussed Limbaugh's calling Fluke a "slut", and said "A far better word might have been 'prostitute' (or a five-letter synonym therefor), but that's still wrong because Ms. Fluke is not in fact demanding to be paid for sex...The right word for that is something much closer to 'extortionist'." Landsburg's comments drew a rebuke from University of Rochester President Joel Seligman, who said he was "outraged that any professor would demean a student in this fashion", and a silent protest from thirty UR students who formed a line between him and his students during one of his classes. In a blog post from March 20, 2013 titled "Censorship, Environmentalism and Steubenville," Landsburg spawned controversy when discussing principles on which to justify what is legal. He proposed as a second attempt that "You can do anything you want as long as you're not causing anybody direct physical harm"; he proceeds to conduct an argument by demonstrating that "it would also allow you to rape an unconscious victim if there were no physical consequences". This outcome, in obvious violation of common sense, is then evidence against the second principle. Critics claim this is an attempt to justify rape on an economic basis. Many students and faculty at the University of Rochester claimed that Landsburg's "thought experiment" was offensive and potentially dangerous, in that it called into question whether or not the rape of unconscious individuals should be illegal. Some protesters pointed out that the young men charged in the Steubenville rape case (to which Landsburg's post directly refers) claimed not to have known that it was illegal to have sex with an
