Thomas Sowell, one of my favorite writers, writes here about how difficult it is to have a rational discussion today about some issues unless one is on the "correct side" of  "politically correct". This should be of interest to most lawyers whose livelihood is dependent, at least in part, on the ability to have a fair chance to present both sides of an issue. He mentions the concept of a military coup, I think, to simply prove his point. (HT: Bainbridge).
