It may be a right, but I am saying you should pass an amendment to guarantee the protection of said right. If you don't then the states should decide.

But why isn’t it already a right?

Is there a constitutional amendment that recognizes the right to a vasectomy or appendectomy?

Why should anyone but myself have any say in what I do with my body?

I'm not saying it isn't a right. The Constitution / amendments do not create rights. I'm saying if you want to guarantee you are allowed to exercise the right you need to pass an amendment.
