Gay rights activists have launched a boycott on social media against the evangelical church behind a march Sunday to protest a new law allowing gay and lesbian couples to marry in the Mexican state of Coahuila.

The protest, which took place in the city of Saltillo, the capital and largest city of Coahuila, came a week and a day after a male gay couple inaugurated the law and a day after the state's first lesbian couple exchanged vows.

A “sea of people” – estimates vary from 10,000 to 30,000 – flooded the city's major streets demanding the law's repeal.

The mega march was organized by the evangelical Cristo Vive Saltillo (Christ Lives Saltillo), which is known for rehabilitating former prisoners, primarily those involved with gangs and drugs, and selling burritos on the city streets.

At Sunday's march, the church handed out pamphlets with the names and photographs of 4 men and 2 women whom it said were former homosexuals.

“We have witnessed miracles,” the flier states. “Yes, change is possible.”

The hashtag #NiUnBurritoMas (not one more burrito) quickly spread on Facebook and Twitter along with religious and comic themes.
