Not sure why you believe erroneously-held opinions when the ACTUAL English law clearly states otherwise.
Probably because you are taking it completely out of context. You don’t seem to understand the difference between someone born in a country, and those born to citizens or subjects outside of the country. Thus you take one sentence and end up facing the wrong direction.
The WKA court discussed the matter at length, citing sources. In context. Context being something birthers aren’t very good at...
Blackstone, 1765:
“The children of aliens, born here in England, are, generally speaking, natural-born subjects, and entitled to all the privileges of such.”

I think I’ll trust his opinion of British law instead of yours...
in 1604 Commons debated a measure to pin down the status of English born progeny of aliens, granting those "of 'the first birth or descent only,' and born within the realm the limited position of a denizen." The House rejected the bill on its third reading.
