I believe that everyone of legal age and mind (and of the human species) should be allowed to get married. Myself personally, I don't ever wish to get married, but for others out there I believe that the right to get married should be available. Screw traditionality, if we stuck by tradition in our everyday lives in other aspects then we would be living like the Amish (no offense meant). We need to evolve and adapt. And besides, what does it matter to you (non-approvers) if some other couple wants to spend the rest of their lives together? It's not your life, so stay out of it.
