it is deranged. the left favors a policy that allows one class of citizen to murder another class of citizen - and a helpless one at that - at will.
That's just what it is --- deranged --- except swap out the word "citizen" for the word "person" or "human being" (since the unborn are not precisely "citizens" until they get their birth certificate. They're kind of like legal residents.)
And by the way, my wonderful pro-life libertarian friend, Doris Gordon, makes this point when debating other libertarians about abortion. She ask whether libertarians believe, in principle, that the State has the authority to create two classes of persons, one with rights and one without.
