The invaluable Nick Milne was an eyewitness to recent fracas with professional bombthrower Ann Coulter and her discontents. He gives a very thorough eyewitness account here. Basic rule of thumb in Canada: free speech for the Correct Sort of People.
Coulter, of course, comes out a winner in such a situation, since she gets free publicity and martyrdom. But brownshirts aren’t too swift on the uptake about such things since they are too busy grunting in Neanderthal self-approval.
