Thousands upon thousands of Guatemalans, Hondurans, Salvadorans, etc., have forced their way into Mexico, intent on forcing their way into the United States. Video at the link.
Yes, we all know this is an election stunt promoted by the American Left, which is paying some of these people.
Here's a radical thought. Rather than walking through Mexico, risking whatever privations and physical harm would be inherent in such a venture, why not stand up against your own s***hole governments and make things better in your own countries? It's clear that you love those countries, given that you're carrying the flags of those countries as you trek towards the United States.
A thought so wacky it just might work.
