Are they against the show for religious reasons, or are they against the idea of a guy liking a show made for young girls? It may come down to asking them, "Why can't you accept me for who I am?" I know you've probably already thought it, but there may be a time when you need to say it. That kind of confrontation may end badly, but in the long run they should come to accept it.

If it was for religious reasons, like the idea of magic in the show being evil, you wouldn't have a chance. With your situation, you just need to make them understand. Explain to them the facts, over 80% of the show's fans are men.
