Fred Phelps is on his deathbed. He's the founder of the Westboro Baptist Church, the gay-hating "church" that pickets funerals.
Phelps has a couple of offspring who are not members of the church and are being shunned. They say that their father has little or no religious belief. The reason he's doing all this is that he has a paraphilia. He's sexually excited by hate.
It's the only explanation that makes any sense.
It'll be interesting to see what happens to the rest of them once the guy croaks.
