Xerxes invading Greece is not akin to modern immigration, and if it at all is, there is this similarity: some Greeks invited Xerxes just as some citizens invite immigrants. My point here is, there were two sides then and now, with reasons for each. In the case of modern times, it is much more complicated because Western countries are and have been unfairly (sometimes wholly) influencing the countries from which people migrate. There has been plenty of colonialism and imperialism from the west; this is not to say there wasn’t imperialism elsewhere, but the west has been dominating like never before. Besides, the problem of the aging populations in the west is really what is driving policy for immigration; so, one ought to blame western culture rather than immigrants who are fulfilling the economic needs that the west regards as the first priority. And in the case of the New World, I welcome immigration to the full, in order to reverse colonization, especially by more native peoples like Mexicans in the United States. I do believe it is Christian thinking to argue that the New World belongs to Europeans—it is entirely foreign to inter-ethnic polytheism that seeks harmony in this troubled, modern world.
