I'm curious as to what kind of conversation he had with God ...

I'm guessing it didn't last long.

Fox News: Fred Phelps Sr., founder of Kansas church known for anti-gay protests at funerals, dies at 84​

I would've edited the title out from in front of his name if I was posting that story, but then, I don't work for Fox.

Phelps was a dichotomy, a riddle wrapped in a mystery inside an enigma. The following information, gleaned from BeliefNet.com, gives full indication of that.

• He was called in 1954 as an associate pastor at Topeka's East Side Baptist Church, an SBC church that is still very influential in the Kansas capitol. East Side planted Westboro a year later and appointed Phelps its pastor. He immediately severed all ties with East Side and the SBC, but couldn't get any other Baptist association or authority to accept his church's membership, so it never had one. He claimed Calvinist and Primitive views.
• He was a disbarred civil rights attorney who committed perjury. That's what got his law license yanked. He was a supporter of Al Gore and held a fundraiser for the then senator from Tennessee when he briefly considered a presidential run. Phelps himself got 15% of the vote in the Kansas Democratic primary for governor in 1998.
• He once wrote a letter to Saddam Hussein praising him for his stance against homosexuals.
  [*]He beat his wife and children with his fists, a leather barber's strop, and an axe handle. The kids beat each other.
• His youngest son Nate fled the church, fled Kansas, fled the country. He's now a taxi driver in British Columbia. He refuses any contact with the family. Nate told a BBC documentary in 2007 that his family was "the most hated family in America," and the program used that as its title.

I'm sorry to speak ill of the dead, but ...

Good Riddance!
