You have obviously not been around many Hell's Angels. They would not appreciate being referred to as gay, and they love their bikes. In any case, as you say there is nothing wrong with it, what exactly is the problem? Granted a lot of gay men love leather outfits, but there are also many gay men who are married to women as a result of family pressure. What would you consider to be worse, an over weight gay man in leathers who loves his bike, or a gay man trapped in a loveless marriage?
