It does not immediately follow that abortion is among the unenumerated rights spoken of in the 9th Amendment. The very question at hand is whether abortion is among the unenumerated rights, so the 9th Amendment merely returns us to the original issue.
...unless of course, one is:
a slave in a slave state
-or-
a perhaps viable, yet still developing human being under the stewardship of one's mother....
Beside the point. What I responded to was this: "maybe now they can go back and see where abortion is listed as a right in the Constitution, as well"
The reasoning being expressed here is that since abortion is not "listed" it is not a right. That's exactly the reasoning the 9th was intended to avoid, which is why I cited it. It invalidates that kind of argument regardless of the particular right in question. It doesn't matter if the alleged right is a legitimate one, that's a different question.
