Proponent and opponents of gay marriage will stage dueling rallies in Paraguay on Saturday.

Just days after Argentina became the first country to legalize gay marriage in Latin America, gay rights group SOMOSGAY (we are gay) announced they would lobby in October for passage of a similar bill in neighboring Paraguay.

With the backing of the Roman Catholic Church, opposition to the yet-to-be-introduced bill quickly mobilized.

“We are going to put out an intense educational campaign on Christian values, to avoid the law of marriage between people of the same sex that was approved in Argentina from coming to Paraguay,” Bishop Adalberto Martinez of San Pedo told La Nation in July.

Saturday's Festival Por La Vida Y La Famalia (Festival For Life & Family) urges opponents of gay marriage to protest the institution at town squares throughout the nation. The group's Facebook page has attracted more than 13,000 followers.

The loudest protest is expected to take place in Asuncion, the nation's largest city and its capital, just a stone's throw away from Argentina.

Gay marriage advocates are gathering in front of the Pantheon of Heroes, Asuncion's memorial to the country's fallen soldiers.

“This festival would not be taking place, if not prompted by the Queremos Papa y Mama (We want a mother and a father) campaign,” Simon Cazal, president of SOMOSGAY, told

At the event's Facebook page, over 1,000 people had agreed to attend Saturday's demonstration.
