If you had actually read my post, you would have seen that I was not arguing for Roe, I was arguing against some post who claimed that the Constitution actually prevents states from enacting liberal abortion laws - which is a blatant falsehood.
"I was arguing against some post who claimed that the Constitution actually prevents states from enacting liberal abortion laws - which is a blatant falsehood."
But the Consitution does actually proscribe states from enacting laws contrary to federal law, in the so-called `premption clause'.
(And the Commerce clause. For better or worse, it's called 'Federalism'.)
Article. IV.
Section. 1. Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof.
As I'm sure you know, the SCOTUS also decided Plessy v. Ferguson, bolstering slavery.
