I gave you a long list of reasons why your idea is bad and rather than engaging a single point against your argument honestly, you impugned me as a xenophobe opposed to all immigration.
You could apologize, or alternatively, actually attempt to support your argument with evidences of thoughtful activity.
Like, perhaps... The possible merits of offering Mexico statehood? I think that is a non starter from both Mexican and USA perspectives, but is at least a far more tenable position than that the People of the United States of America should feel a cumpulsion to deprive ourselves of our sovereignty.
Such a compulsion is better treated with antidepressants than self destructive legislation.
