This is what happens when you let citizens of another country come in, and there is no requirement for them to learn your language. The reason illegals and their supporters could put all this together under the radar is because they organized it all on Spanish radio and television. Few English speakers listen to the Spanish radio or watch Spanish TV.
Those of us who live on the border were not surprised. We have been trying to tell the country for years that there are many many more illegals than anyone realizes, that they are not assimilating, that they are trying to reconquer the Southwest, they believe it is their land. No one would listen. If they had listened instead of accusing us of being racists, no one would have been surprised. I hope people are listening now, because the hour is really late and a solution needs to be found. A major fence/barrier should be being built as we speak.
We are not in the corner yet, but if drastic steps are not taken we soon might be. Mexican War II is starting and the US is late to the party.
