This was a great comment:
If you're Catholic, and you want to follow the RCC's teaching about same-sex marriage, I strongly encourage you to live your faith and not marry somebody of the same sex.
Otherwise, please mind your own business. Or pray for your deity of preference to make your religion the official State religion. Because that's worked out so well in the past.
Then, on the other side with a rebuttal:
Corrections to this article Part I
A) I can’t really be married to a same sex person, for the same reason that I can’t flap my arms and fly. Nature makes some things have certain functions, and calls them birds. They are different than humans. No amount of saying you are a bird will make you one. Nature makes male and female animals function in certain ways. Those ways don’t work right unless one animal is female and one is male. No amount of saying that 2 animals of the same gender are the same as a male and female pair will make it so, even if the government says it is so. Governments can’t make 2 + 2 = 5 by saying so.
B). It is not about a religious belief. It is a fact of life like the birds and the bees. That’s just the way it works. Make up a new name for your clearly different thing, and we can all get along.
Nature makes over 1500 species that exhibit homosexual behaviour, try again.
