While Ugandan President Museveni accuses the United States of trying to import social imperialism into Uganda by defending homosexual rights, who do you think is behind some of the anti-gay hysteria in Uganda right now?

A group of evangelical Christians from that very same hotbed of social imperialism: the United States of America.

Museveni on Monday signed into law a bill that toughens penalties against gay people and defines some homosexual acts as crimes punishable by life in prison.

Roger Ross Williams belonged to an organization called International House of Prayer in Missouri, whose missionary zeal fell on gays in Uganda. He decided to make a film about what he learned called “God Loves Uganda.”

Someone like evangelist Scott Lively is “an extremist in America,” Williams said, “but when he goes to Uganda he gets taken seriously because of what he represents.”

“He’s an American evangelical, and what an American represents in a place like Uganda – it represents power and wealth.”

“So he goes to Uganda and he can command the president, he can command the parliament for five hours. He did a three-day conference, where he told everyone about the threat of homosexuality, that they were there to recruit their children.”

“And that’s what really sort of started this whole bill on its, where it is now, today, this sort of tragic day.”
