As one who has lived abroad a long time, I can simply affirm that one's cultural and national identity are heavier than a passport. Murdoch spent much of his childhood and early adult life in Australia, where he still owns property, operates going concerns, and where more than one of his own children live.
Don't take my comment wrong. I'm not rejecting foreigners in America or anywhere else. I recognize my family's own European origins and humanity's migrant nature.
But I will say, particular to Murdoch, that I wish he had stayed in Australia, and I'm sure many Americans share my sentiment. He has had a vicious influence on this country's foreign and domestic policy, which has cost many innocent lives, and he has grown rich off it. A modern-day Hearst, and a shame...
