A conference in Uganda which begins today has been condemned by human rights groups.

The 3-day seminar in Kampala, which opens today, features several American speakers known for their efforts to dehumanise LGBT people and for their belief that homosexuality can be “cured.”

The speakers include Scott Lively, Don Schmierer, and Caleb Lee Brundidge—leading voices in the crusade by religious extremists to roll back basic human rights for LGBT people in the United States.

IGLHRC said that Brundidge is affiliated with Extreme Prophetic Ministry in Phoenix, Arizona. Schmierer is on the board of the so-called “ex-gay” organization Exodus International. Lively is well known for his belief that the Nazi Holocaust never happened.

“The American religious right is finally showing its hand and revealing the depth of its support for homophobia in Africa,” said IGLHRC’s Executive Director Cary Alan Johnson.
