OK, I looked it up myself, Voices of the Frontier.
Apparently they believe that the frontier of Mexico is in WI.
Just the name of the organization should get the attention of anyone with any sense.
This is colonization, not immigration.
Frontera also means “border” and is where we get our word frontier. Frontier in American English connotes pioneering. But in the French and Spanish, it just means border, or line.
