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?
Australia made it legal and so it should be. I am not gay but what has it got to do with me or anyone else how another human sees the same sex. Absolutely none of my business. If two people love each other and want to make a commitment then good luck to them, we are in the year 2018 not 1918.
