I'm sorry to say that reality does not agree with you. You state as fact that homosexuality is not natural but you don't back it up at all. It's just a dogmatic statement. Observations of nature and human history flatly contradict you.

Your statement that gay people can't form lasting unions without gay marriage is also simply false. It is of course true that not sll gay relationships last, and that some gay people sleep around, but that's no different than straight people. Just look at the divorce rate! However, your statement proves my point that gay couples need to take part in society more and refuse to be bullied into hiding.

From a personal point of view, I am in a long-term stable relationship and I don't have or need a piece of paper to make it work. What I need the piece of paper for are the practicalities of life that staight married couples take for granted like inheritance rights and visitation rights.
