> Thus they imply that a few cells (under some state laws this would be from the moment of fertilization) have rights that supersede (or at least conflict) with an actual person's right to have their liberty protected from the State.

This is a bizarre misreading. It doesn't say that. It says that the Constitution does not grant them the power to invalidate a state law against abortion, because Roe erred in determining that the 14th Amendment right to privacy entailed a right to abort a pregnancy.

(I'm not against abortion, for the record, but I'm increasingly disappointed with the facile arguments I hear about it. Of course this Supreme Court decision is not a 'religious decision that the fetus is a human being', my God.)
