Don't worry about them. Stay just as happy as you are.

Reminds me of this comic I saw once. These guys were talking about what sports they played and one was a male cheerleader. They all laughed but then the next panel shows him at a game surrounded by these cute female cheerleaders and you can tell that the guys who laughed are jealous.

People will find something to tease about no matter what you do, might as well do what you like.
