Anti-gay pastor Scott Lively angrily challenged Last Week Tonight host John Oliver to a debate after Oliver featured him as part of a segment on U.S. Christian influence on Uganda's draconian restrictions on homosexuality, Right Wing Watch reported.

"I'm calling out John Oliver as a liar and a fraud who couldn't go ten minutes with me in an unscripted, unedited debate," Lively posted on his blog. "Without his teleprompter and his cheap-shot, out-of-context video clips he would be exposed as just another left-wing loony."

Oliver mentioned on his show this week that Lively was allowed to address Uganda legislators for five hours before the laws were implemented.

Oliver showed footage on Sunday of Lively calling homosexuality and pedophilia "equatable" and comparing the LGBT communities to Nazis and the forces responsible for the genocidal attacks against the Tutsi tribe in Ruanda in 1994, saying American Christian conservatives were moving to spread their opposition to same-sex marriage and other issues to counteract the rise in acceptance for marriage equality.

"Clearly, U.S. groups recognize the market for homophobia stateside was dwindling, and so tried to sell it somewhere else," Oliver said. "Meaning that Africa isn't just where we send our losing teams' Super Bowl shirts -- it's also where we send our losing political philosophies."

Lively accused Oliver on his blog of misrepresenting him, though he did not name any specific instance of it. For instance, a clip Oliver showed of Lively saying President Barack Obama "may well be a homosexual himself" was already public knowledge. And Right Wing Watch has reported on Lively's previous attempts to distance himself from the law.

"Oliver is lying through selective editing re Rwanda and several other points," Lively wrote. "His show was one continuous stream of malicious LGBT propaganda in the guise of comedy."
