You believe that the constitution provides marriage as a human right, because the Court, a small group interpreted that, though marriage is not mentioned in the constitution.
Look, it's simple. The Constitution says all laws must apply equally and that they cannot, without compelling state reason, be partial. The Constitution also doesn't mention cars, the FCC or airplanes, yet there are laws about them that apply equally to everyone also. Why are you not getting that?
However, the Bible says to abstain from blood, and another small group interpret that to mean blood transfusions also, but you don't accept that.
I'm an atheist, love, why would I?
