The fact that it was removed is accurate, the reason for that is quite speculative.
You stated in an earlier post that the Nationality Act of 1790, which declared children born abroad to US Citizen were 'natural born Citizens' of the United States -
"This precedes your court case by some 100 years and certainly illustrates with clarity the mindset of the framers concerning this very issue.."
I'm simply stating the same. Since the Nationality Act of 1795 removed the text that declared children born abroad to US citizens to be 'natural born Citizens', that it "illustrates with clarity the mindset of the framers concerning this very issue" - that they did not consider such children 'natural born Citizens'.
Or perhaps they “removed” it because it didn’t belong under the heading “naturalization” or that it was self evident or whatever.....
Speculations as to motive is generally pretty soft ground.
