CAPE TOWN, South Africa (AP) — Conservative U.S. Christian groups are setting up fronts in Africa to fight for anti-gay and anti-abortion legislation to promote their convictions, a report by a Boston-based think tank said Tuesday.

It accuses evangelical stars such as Pat Robertson and Rick Warren as well as Catholic and Mormon groups of setting up institutions and campaigns in Africa that are “fanning the flames of the culture wars over homosexuality and abortion by backing prominent African campaigners and political leaders.”

The report — “Colonizing African Values: How the U.S. Christian Right is Transforming Sexual Politics in Africa” — was presented by the Political Research Associates of Boston, a think tank that describes itself as “progressive” and focusing on what it calls attacks on civil liberties by the political and Christian right.
