So a bunch of turd-worlders are killing people and this reflects on Roman Catholicism exactly how? Did the Pope issue an Encyclical authorizing this? No, he did not. Did Mexico’s Cardinal issue an Encyclical authorizing this? No, he did not. Did a bunch of communist rebels in Chiapas murder people under the color of religion? Yes, they did.
Mexico isn’t even a Catholic country anymore! The socialist revolution there in the first part of the 20th century devastated Catholicism there, and most folk north of the border have no idea.
