Some countries or state have been accepting this kind of marriage. Here in the Philippines, we do not recognize it as legal or something like that. How about in your country?
I don't think it is appropriate, maybe it is the norm of every individual to be loved and be loved in whatever form. But it will be unacceptable to marry two same sex person. It will be too displeasing to God.. Maybe they can live together show they're love to each other but never swear their love in front of God.
