To my personal view, its's entirely uncacceptable in any society.
The term "marriage" is often defined as the combination between two opposite sex. It means that it claims two different elements modified or complemented together for having the following consequences. Talking about "marriage", one frequently thinks about love, delivery, family, duty etc...
I am suspicious of a real love in the marrage of the same sex. Do they have anything offered together? Do they come with each other through a real love ? Of course they themselves - gay, lesbians- might have lots of reasons to explain their actions as well as the meaning of "real love".
No bad consequences have been found scientifically from marriage of the same sex. It's just regarded as something unusual in a morden society. But some developed countires approved it officially, and people looks tolerant towards such couples involved. Sex story is a quite private thing and which way to choose in marriage is also private.
Actually, why we forbid such unnatural marriage legally and constitutionally ? It might be contradictory to our current views but how can we know in future or a few more years ?
Marriage of the same sex brings no notion of "husband", "wife","dad" "mother", "kids", "uncle", "aunt". It seems to upset all of ordinary conception that has often been recognized as common standard for a happy family.
The topic given by Lenny TRAN is quite wide, not limited and commented in just few messages. The problem is that we should not condemn it as anything horrible like many asian countries have. It is neccessary to have an appropriate resolution to it rather than expressing morally disapprovals against it.
