Mexicans make great Americans. They are not here to convert us to some other form of govt or religion. They are here to participate in what we are. Simply stated, there is not a better ally in the world than a Mexican become American. They are a friendly loving devoted and loyal people. What's the problem? I say we need them...served with them...and know their loyalty.
What's the problem? If you see no problem with literally millions, entering our country illegally, routinely, at will, then there is nothing I can say that will convince you that there is a problem.
