No, it doesn't. It is simply the idea that the legal impact of an enactment is set by the meaning (for the textualist form or originalism) or intent (for the intentionalist form of originalism) of the law when passed (whether you are referring to a statute or the Constitution or anything else.)
It has nothing to do with belief about the merits of the Constitution prior to subsequent amendments.
Why else? Point me at someone who believes the Constitution is deeply, deeply flawed and in serious need of major revisions yet takes an originalist approach in their jurisprudence.
All of the people who supported amendments?
Given that, despite the cases that get the most public attention at the highest levels, most judicial interpretation isn’t of the Constitution, that doesn't make sense; it also doesn't make sense otherwise, since the Constitution has had extensive (either from a textualist or an intentionalist perspective) radical changes within the perspective of originalism, so originalism is in no way incompatible with believing the 1789 Constitution needed major revision, even if one assumes that an originalist must be operating ends-first and looking to rationalize their desired end-state of Constitutional law, rather than honestly.
You're missing my point. And I don't care right now.
The 13th, actually (it determined how chattel slaves were counted in apportionment, and the 13th abolished chattel slavery, so there were no chattel slaves to count.)
(And, yeah, there's actually more than two ways to interpret the Constituion.)
(I think both forms of originalism are useful and important interpretive lenses, but I think taking either as universally decisive or even mistaking either for a decidable objective standard is deeply problematic.)
And this display a crucial point, there is a legal process to amend the Constitution not relying on a few scholars re-re-re-interpretation. I'm all for a Constitutional Amendment on abortion, as long as it's the Will of the People, not the Will of a few jurists. If you can get a Constitutional Amendment for the prohibition of intoxicating beverages, you can certainly get a Constitutional Amendment behind abortion... unless it's less of a consensus as you make it seems. Also, using one's 14th Amendment Right to privacy to "legalize" abortion is a pretty weak argument.
