"Anyway, isn't that like good friends except sensuality added in?"
I wanted to comment on this part. Gay lovers are just "sensual good friends"? My wife and I are best friends. And lovers. I don't see how (outside of Christianity) that my marriage is any different than a gay relationship.
By the way, here in Texas, and many other states, we have what is called "common-law" marriage. These people have never gone to a church or courthouse to get married. But if they are together for a certain time, and introduce themselves as husband and wife, then for all intents and purposes, they are married! They can get all the benefits, life insurance, etc. Not only that... without having ever been officially "married," when something turns sour, they have to get a real divorce! Lawyers, child support, alimony... Why can people that aren't offically married get benefits when gay couples can't?
