I would like to reply that both your assumptions are wrong. 1) a state has the right to deny marriage on any grounds other than religion, race or nationality.

I would like to reply that both your assumptions are wrong. 1) a state has the right to deny marriage on any grounds other than religion, race or nationality. So a state has the right to impose conditions on marriage that have to do with gender. Hell, the treaty almost says that a state has to impose some limits (without specifying what those limits are) Article 16 UDHR (paragraph 3) 2) You DO NOT have the right to treat either adult different because of their political opinion EVEN IF IT DID VIOLATE HUMAN RIGHTS. Article 1 and 2 UDHR So not only did both of these individuals not violate human rights, you did.
