In 2001, I signed a petition on internet for the Federal definition of marriage to be between a man and a woman. The sad think was that I didn't reralize at the time that it would ban not only same sex "marriages", but perhaps also poligamy.
Same sex "marriage" does not exist. Even if a State recognises it, it's not marriage. We can pass a biil saying the the Sun is square, but it'll just remain round. LOL.
Now, if gays living together want to enjoy some of the benefits usually awarded to marriages like sharing health care or inheriting the other, the question could be easily solved without involving sexual isues. What about straight people who might also live together and want the same benefits? Two single old aged brothers or sisters, two friends, etc.... Perhaps, there should be a legal contract for persons who live together including those who have no sexual issues.
The problem now, is not exactly gay "marriage", but gay adoption. Many countries which haven't approved those "marriages" are allowing those adoptions. That must be stopped. And the other problem is adoption by singles because many gays or lesbians singles adopt a child. There should be a law banning adoptions by singles who, due to their sexual preferences or any other reason, have no chance of marriying a person of the ooposite sex in the near future.
