I have no idea who Fred Phelps is, but the pic still made me laugh.
-S
Phelps runs an extreme right-wing church comprised almost entirely of family members. He pickets at the funerals of gay people, and demonstrates out in front anything he perceives as 'gay-friendly' (ie: school plays with gay characters, etc.)
He's a nut job who has no scruples about dragging children around with him to hold up these extremely homophobic, hate-filled, day-glow signs of his. He's also, most likely, a closeted homosexual, as pointed out by the two gentlemen standing next to him.
