“The 14th Amendment was an act of congress until it was ratified by the states, and it became an Amendment.”
No, your insults are not arguments. An act of Congress is a LAW. A proposed amendment, not ratified by the states, is NOTHING but proposed wording.
And the 14th Amendment, having been ratified, is the CONSTITUTION, not an act of Congress. And when Scalia contrasted acts of Congress as the basis for citizenship vs an act of Congress, the 14th is CONSTITUTION, not an act of Congress.
The quote you provided earlier from Scalia didn't say anything about 'acts' of Congress, just about citizenship being conferred by Congress. The 14th amendment would be a case of Congress conferring citizenship.
