I hear you, its true how difficult it is. When I was growing up my family would actually turn off a movie if it had a groin kick in it! In the past few months I've heard fetish stuff mentioned more than usual and it almos always goes beyond just joking about something you don't like and is often extremely derogatory and belittling to whomever is into it, surprising as I thought my fellow Montrealers were a bit more open-minded. Lately I'm starting to care less and less if I get found out though, it could be very entertaining and a good way to find out who your real friends and who the social posers are (easy to say, hard to do, when you're in a situation, i know)
