Gay Marriage Arriving in Mexico City

The same-sex Mexican wedding will be born tomorrow as a new law puts Mexico City on the front lines of the gay marriage battle raging across Latin America. But even as gay couples line up to tie the knot, the Catholic Church and President Felipe Calderon's conservative party are gearing up to fight the law, the Washington Post reports.

Same-sex unions are legal in Colombia, Uruguay, Brazil, and Ecuador, as well as Argentina, where two gay men wed in December, but Mexico City is the first place south of the border to formally allow gay marriage. A local cardinal blasted the law as "perverse" and Calderon said it violates the Mexican constitution, which "speaks explicitly of marriage between a man and a woman," but advocates note there has been no popular backlash against gay marriage in the city.
