We learn from this IHE piece that Harvard economist Subramanian Swamy was apparently pretty distressed by last summer's hotel bombing in Mumbai, India by Muslim extremists. Swamy gave full vent to his feelings in a lengthy op ed piece there, arguing that Muslim terrorists were his native land's most pressing security problem. Shortly thereafter, he was in big trouble at Harvard where a group of Muslim students took offense and demanded that the university terminate his employment immediately. That didn't happen, but his faculty colleagues did an end-around by removing Swamy from the two courses he was slated to teach in the summer session for 2012. So: he hasn't been sacked, but he can't teach at Harvard either. His views, as one administrator termed them, are "destructive."
I'll certainly grant you that they're controversial, but also well within the limits of controversy that an academic institution ought to be able to tolerate. It's good to see that many commenters in the response thread agree.
