A former federal Liberal candidate in B.C. sparked a firestorm of criticism Thursday when he called Vancouver’s Pride Parade “vulgar” in a Twitter post. Shinder Purewal, a professor at B.C.’s Kwantlen University, ran for the Grits in Surrey-North during last May’s campaign. “Vancouver’s so-called Pride Parade should be banned. It is vulgar…to say the least!” Purewal tweeted Thursday. Purewal later said he is not homophobic–he supports same-sex marriage–but he is opposed to overt public displays of sexuality.
