It is all they have to do. They're a personality cult centered around Phelps, and Phelps is completely obsessed with his "protests." He literally thinks he's a vengeful prophet and/or the new Messiah and that he's doing battle against the devil.He's not just anti-gay either (though we're his favorite apparently). He's almost as viciously anti-Jewish. His mission is to have all queer people and all Jewish people killed. He thinks all military defeats and natural disasters are the result of God punishing America/humanity for continued failure to execute us.This is a guy who's (still) trying to raise money to build a monument to the goddamn tsunami, in honor of it killing Swedish tourists. Nevermind all the (predominantly Muslim) local people who died, they're irrelevant, but apparently Swedes are all gay and God sent a big wave to kill them all.He also showed up after a West Virginia mine cave-in that killed a bunch of men, with signs saying "Thank God for dead miners." And at the funerals of Iraq war dead with pictures of soldiers photoshopped into hell.He's insane. They're all insane. Not in the normal, metaphorical/insult "you're insane" kind of way. In the Jim Jones/Charles Manson kind of way.
