A right is a shortcut in consequentialism (or another normative ethics) turned into a lost purpose. Different rights can and do contradict each other, since they were derived in different circumstances. Thus you can argue for or against anything, by stretching the domain of validity of a suitable right. It all depends on how connected, influential and persuasive you are. Hence lawyers.
What'd be the difference between that and an ethical injunction?
