Universal human rights are inalienable.

Distinction is always going to be less effective than universally agreed declaration. We can declare: all human beings have equal rights.

Pandora's box is the universality aspect, which must be manifest by those agreeing to declare the nature of ones rights in respect to others rights, both for oneself and for others. This is the reason a distinction-based legal position is poor policy.

We cannot distinguish between a man and a woman if we are agreeing to the universality of their equal human rights.

The we part is the difficult part, apropos pandora's boxes. But ultimately, universality is very empowering to the individual.
