The duty of our Government is to the American people--not to some sort of abstract view of humanity. The idea of one humanity is a bit of confused collectivist/egalitarian fluff.
The Constitution starts out with a Preamble, which makes it very clear that America is about the Americans & their posterity. As the descendant of immigrants who arrived after the War for Independence, I am very grateful to be here; but I know that my duty is to preserve the land, culture & population that permitted my forebears to settle here. Biting the hand that extended hospitality, because one thinks it should extend even more hospitality to those who do not even want to embrace American culture, is contemptible. But with so many "pundits" intoning to the contrary, Mrs. Rubio can be forgiven for her remarks. That does not mean that we should not in, a kindly manner, explain why her position is fundamentally wrong. I am sure that she is a very nice lady.

Yes, Mrs Rubio can be forgiven. But she needs to understand 98% of North Koreans would move here if they could - and they would also be grateful...and hard working...
