The pope's comments in support of gay civil unions did not go far enough and could even harm the campaign for same-sex marriage, LGBT+ rights campaigners said on Thursday.

In a documentary called "Francesco" released on Wednesday, the pontiff said that gay couples needed legal rights and that "homosexual people have a right to be in a family", some of his clearest language on the subject since his election in 2013.

But after years of opposition by the Catholic Church to gay sex and same-sex marriage, the pope's comments will do little to advance LGBT+ rights or repair the damage done to gay people, LGBT+ campaigners in majority-Catholic Latin America said.

"Given the church's history, I don't believe that this approach is one of inclusion with respect to the rights of the LGBT population," said Diane Rodriguez, president of the Ecuadorian Federation of LGBTI Organizations. "This is more like a wink of the eye, it's not like saying LGBT people should be loved and welcomed."

The Catholic Church teaches that same-sex attraction is not sinful, but homosexual acts are, even though LGBT+ people should be treated with dignity. Following a high court ruling that was publicly rejected by Catholic church leaders, Ecuador legalised gay marriage last year, one of 28 countries to do so.

LGBT+ rights activists said the pope's support for civil unions could undermine the campaign for gay marriage in some countries by suggesting a kind of 'separate but equal' alternative. Read more via Openly/Reuters
