And if you must know, I consider irrational something silly like "It's unnatural.", or "God doesn't want it.", "It sets a bad example.", "I don't want children exposed to it.".
My opinion is, I'm fine with it.
I'm personally heterosexual, however I see no reason to dislike them. A man loves another man or a woman loves another, and that's a beautiful thing they should keep, and should display it marriage.
So, I am proud to live in a country that homosexual marriage is legalised.
Although on the religious debate, I believe that a priest is entitled to their own choice, though quite why a strand of Christianity that doesn't support the Bible which so strictly, given plenty of God's instated rules are broken.
