There are actual amendments concerning slavery.
I am VERY pro life, but I think it's a states issue - not a national one.
Granted, from a practical point of view, it looks like we'll have to knock down Roe and then slug it out state by state. But as a matter of principle, there are also "actual amendments" concerning the right to life (Fifth Amendment: No person shall be...deprived of life, liberty, or property, without due process of law) which ought to apply to every human being without regard to age or condition of dependency.
