So your father is giving you guff for liking FiM? I think your best bet is to ignore it and stay classy about it. If your father calls you gay (which is a pretty deplorable thing for him to say, even in jest), smile and tell him you are straight (if you are). It sounds like the females in your family understand you and accept it, so maybe you should talk to them about your feelings -- maybe if you have a "united front" you all can tell your dad that the way he's treating you isn't fair. Whatever happens, take pride in what you enjoy, and don't let anyone tell you otherwise!
