Peruvian congressman and former pastor Julio Rosas is pictured after a ceremony of Peru's Christian Evangelical churches with political leaders in Lima, July 30, 2014. Losing the fight against same-sex marriage at home, leading U.S. Evangelical Christians are joining in the culture wars in Latin America as cheerleaders for opponents of gay legal partnerships, abortion and pornography. The many left-leaning governments in Latin America will not be easily swayed by U.S.-backed conservatives and the fight against gay marriage has already been lost in Argentina, Uruguay and Mexico City, which have legalized it in the last four years. But the alliance of U.S. and Latin American Evangelicals is having some success in Peru, where Rosas, a conservative lawmaker who is an NHCLC/CONELA officeholder, is blocking a bill in Congress that would allow gay civil unions.
