First time i've seen (E) as an argument. I had been wondering about this because there were LARGE numbers of British Loyalists in the Colonies after the war. Were THEY British subjects, or forcibly American citizens? Good Point.
On a secondary note, I've recently discovered two legal scholars (others may have already known of them) that argue the Expatriation act of 1868 demonstrates conclusively that the writers of the 14th completely abrogated English Common law as the basis of American Citizenship. Here is a link to testimony before the House of Representatives (in 1997) by one of the Legal Scholars.
Another line of attack. :)
