re: Natural rights
There can be no "right" that demands violating the natural rights of another human being.
Not true. Civil rights often trump natural rights in American society. Restaurant owners aren't allowed to engage in racial discrimination, for example. If George Bush wants to build a ballpark on your property, he can
have it condemned, pay you off and take it, his civil rights trumping your natural right to property.
And there are people (mostly religious nuts) who believe the unborn conceptus is a human being whose natural right to life demands violating the natural rights of the woman carrying it.
