hey, a right is a right, the anti-abortion folks just need to deal with it.
the heller decision said that the government has the right to restrict gun ownership in certain circumstances, therefore there is no such thing as an absolute right.
and before the inevitable jumping on the invocation of the abortion argument happens, roe v. wade established that a woman has a 9th and 14th amendment right to get an abortion, but also that the state has a right to limit it in certain circumstances. in this case, abortion is a constitutionally protected right, even if it is not proscribed in the constitution, which is why the only abortion clinic in mississippi is open today despite that state's legislature trying to shut it down.
Seems to me that this would be a GOOD requirement, safety of the mother and all that... None of the physicians practicing there have admitting privileges to any hospital. Now I have not looked into that particular matter very much, but at first glance it looks fine to me.
Unlike your abortion straw argument, the right to keep and bear arms IS specifically guaranteed in the black letter writings of the Constitution, not derived from the "emanations of the penumbra".
