The reason that so many Mexicans live in the American Southwest is that the region is really Northwest MEXICO. The USA stole the region as the result of a war of aggression that occurred after the Texas slavers staged a revolt in 1836 (the Mexicans were going to force them to liberate their slaves and the Texas racists didn’t want that at all). Mexico has never given up its claim to its ancient territory. Do think on that when you hear the demented “conservatives” rant on and on.
Be careful what you wish for… you may get it, and in its fullness. Have a care…
