“how the Children of British subjects born in America are not British Subjects”?
According to English law they WERE. England thought that Americans were legally English until 1815. Between the adoption of the Constitution in 1787 and the end of the war of 1812 - in 1815 - Presidents Fillmore, Pierce, Buchanan, Lincoln and Johnson were all born.
Were none of these U.S. Presidents qualified because England considered them English according to English law?
Not English Common law. English STATUTORY law. Get it right.

If we had been respecting English Law, then the answer is "yes." Since we didn't respect English law, and had instead replaced it with American law, the answer is "no."
