Standing onstage in black velvet robes, despite the stifling heat in the open-air church, Pastor Martin Ssempa's face is a mask of disgust.
"Anal licking!," he shouts, directing the crowd's attention to the images of hardcore gay pornography that he's projecting via his laptop. "That is what they are doing in the privacy of their bedrooms."
"Everything having to do with eating of poop…heterosexuals do not eat poop," Ssempa said. "And if they do, they are misguided, they are not real heterosexuals. We don't practice, that's an abomination. It's like sex with a dog, sex with a cow; it's evil."
Ssempa's animated style has made him one of the most popular preachers in the African nation of Uganda. But it's his virulent homophobia that's put him at the center of an international uproar. The pornographic images, which reduced some of the churchgoers to tears, were meant to whip up support for a bill under consideration in Uganda that would make some gays and lesbians eligible for the death penalty.
The bill was introduced several months after a visit by several American evangelicals, who spoke at a conference called the "Seminar on Exposing the Homosexual Agenda."
One of them was Scott Lively, a pastor from Springfield, MA, who believes that countries like Uganda can still protect themselves from what he sees as the scourge of the gay agenda.
"These are good Christians; better Christians than there are here in the states," says Lively. "They care about each other. And I think the reason they're pushing so hard on this law is that they don't want to see what happened to our country happen over there."
He told the conference's audience, made up of teachers, social workers, and politicians that "even though the majority of homosexuals are not oriented towards young people, there's a significant number who are. And when they see a child from a broken home, it's like they have a flashing neon sign over their head."
Lively, who is the president of Defend the Family, is also the author of a book called "The Pink Swastika", which argues that the Nazi Party was a homosexual movement.
"If you deny and reject the design of your own body," he told the conference, "and you engage in conduct that is self-evidentiary wrong and harmful to you, then you're going to receive in your body the penalty which is appropriate. Can anyone say AIDS?"
Also at the seminar were two American men who claim gays and lesbians can be healed, including Caleb Brundidge, a minister who says he lived as a gay man for ten years.
"I say that no one is born gay and anyone who wants to change can," said Brundidge, who works for the International Healing Foundation. "No one that has same sex attraction, they didn't choose to have that. I'm living proof. Change is possible. I changed from that lifestyle to the one I'm in now. That's not a gay lifestyle, it's a straight lifestyle."
Brundidge was joined by Don Schmierer, who serves on the board of Exodus International, another group that works with people who want to reverse their homosexual attractions. Schmierer declined to be interviewed by ABC News.
While there, the three American Christians also met with members of the Ugandan parliament.
Months later, a bill was introduced called The Anti-Homosexuality Bill of 2009.
