The answer to the mythical Atzlan if (as seems utterly unlikely) it ever becomes an actual threat is the vigorous application of US military force but we don't need to waste resources having the military posing as F troop resisting those "terrorist" Mexican mamacitas when they are needed in the Middle East and elsewhere to kill our nation's actual enemies. BTW, the Second Amendment RTKBA will also come into play as necessary to thwart any Atzlan fantasies.
My maternal (Scottish/Scots-Irish) grandfather came across the border on foot from Canada in about 1901 and had no "papers." Look how I turned out. You might want to be more careful about those Canadians.
This country has allowed the murder of 50 million innocent infants by abortion. The Mexicans and other Hispanics are making up about half of that deficit to date and are working diligently on making up the other half. God bless them and may they prosper in spite of the childish whining of their nativist neo-KnowNothing enemies.
What's next as an allegedly conservative cause? A revival of the KKK??? The unofficial "border patrol" newsletters attacked the late John Paul II for diminishing the importance of national boundaries when they clash with human rights. Of course, JP II was a 19-year old youth in Poland, an altar boy serving the last Mass for several years at the cathedral when the nazis and communists invaded on a September day of 1939 and had a lot of experience with bordermania run amok but that does not matter to some bordernuts who seem to be anti-Catholic while they are at it.
Just because the Canadians know better than to try a Canadian form of Atzlan (and under the current Canadian government are pro-American unlike their last government) does not mean that they have tight enough security or firm enough determination to keep terrorists like the 9/11 hijackers from coming across our northern border. Until we protect the northern border, the conclusion is inescapable that the real concern of bordermania is that its practitioners see some social difference between themselves, their idea of America and the Mexicans and other Hispanics crossing our border.
A lot more people than you may suspect see the United States as a great nation that has absorbed wave after wave of immigrants to our benefit and theirs and will continue to do so despite the ever present caucus of those who, incapable of being comforted, whine uncontrollably and rage against the reality and necessity of refreshing our republic by the influx of those whose highest earthly ambition is to be Americans and part of the American Dream. We are a greater nation than that. Our nation is far greater than those who would surround it with a Berlin Wall.
Your grandchildren, if permitted to know where you stood on this matter, will be ashamed of you.
