I don't think people should protest his funeral. The whole reason the WBC does what they do is to get attention. They think everyone is going to hell including them so they want everyone to know about it, and the only way they can is by being horrible people. If people were to protest Fred Phelps' funeral it would get them even more attention and add fuel to the fire. There is no way to go about it that won't make everything worse than it already is.
