Nice try, Nintendude, but they don't listen to anyone. People have sent them all kinds of well-thought-out emails, and their responses are things like, "No, you're all wrong, God isn't loving and merciful, he's actually an angry and jealous God! rawrrr."
I think it's a shame that good Christians or even religious people have to be lumped in together with people who hate like the WBC. Personally, I believe in a godlike force or entity, but I'm not of any religion. I don't believe in organized religion, but I'm cool with people following whatever they want as long as it doesn't hurt people. And unfortunately, that's what the WBC does. They say things and they do things that I am very much against. They hurt a lot of people. Unfortunately, they have freedom of speech on their side.
But, man oh man. I wish, I wish wish WISH I was making my Prophet costume and could run into them. Oh, how the lulz would ensue!
