At this weekend’s annual celebration of gay pride in Vancouver, B.C., the highlight will be a big and joyous parade, an event which should, based on last year’s numbers, draw more than 600,000 people – my son Sam being among them. Sam will drive up from Seattle during what is a way-too-busy season for him because, as he says, “I like who I am and, frankly, I like to go to a good party.”
