I do not care about same-sex marriage.

It is Individual matter, and government has nothing to do with it.

Overall I denounce any sort of legalization of marriage, it is useless.

What can be legitimate and proper and sacrosanct is the "Contract" base of a mutually beneficial relation.

The member of couple (same sex or opposite sex) can make a proper reasonable, mutually beneficial and flexible deal before going in a/any relation. The breach of that "Contract" will amount to be a punishable fault.

There's no use or necessity for the so-called legitimacy or illlegitimacy of a relation, a "Contract: made on mutual consent between two independent people is however legitimately deserving protection and respect from each of them and all of the society too.

I denounce the system of marriage! And I assert the importance of the "contract" between two free adult citizens(same sex or opposite sex) on their own accord. Government or social law bodies has nothing to say or do about it. On the other hand, it is duty of the government and law bodies to save the importance and the individual interests of the couple based on that mutually beneficial "Contract".
