Your observation changes nothing, I was aware of what I was saying. And I did not say invalidates Gay marriage. I said it is was impossible. Gay love and union validates itself. Nonetheless, it is a different thing than marriage. And you do come close to understanding my argument, there is no objective, empirical definition of love that marriage can be based upon. And saying that the love of a man and a woman in marriage is absolutely different than the love of gay unions is not mutually exclusive, but obvious. The loves work in and express in different environments that are mutually exclusive and therefore must create exclusive conclusions.
It isn't that hard to understand.
