From The Globe And Mail:

Mr. Arron said he tried to get Mr. Harper to give a clear answer [on whether he would use the notwithstanding clause to take away the Charter rights of gay and lesbian Canadians] at a rally in Guelph, which he was attending with volunteer Bob Smyth.

Mr. Arron was shouted down by cries of “shut up, shut up.”

Tory supporters then hit Mr. Smyth with signs and an elderly man punched him in the face before police intervened.

This is the level to which social activism in Canada has been reduced: heckles from the left and punches from the right. Those who scream the loudest and shrillest will win. Animals, all of you!
