Another pointless question.Let's get back to the basics.
Gays exist. Always have. What they do is their own business just like what heterosexuals do is their own business.
It's only if an individuals actions are truly harmful or illegal do we interfere as a community in terms of individual freedoms within the confines of the United States.
The fact gays are attracted to and have sex with adult members of their own sex is a non-issue given heterosexuals are allowed the same in terms of their personal lives.
This biased roadblock to nationwide availability for gays to marry is based on prejudice. Plain and simple. And for that alone it needs to be abolished.
Now if anyone disagrees with gays marrying the solution is simple. Find harm in it. Otherwise step aside of move to a country where the citizen's rights of said country don't come first.
The first question that anyone with common sense would ask is, "Are they the same?"
From any point of view, the answer is no.
From the very basic essence of science, marriage is a cross cultural constraint on evolutionary mating behavior.
Ss couples are a defective failure of mating behavior. Literally 'unmarriage'. Only ever a mutually sterile, pointlessly duplicate gendered half of marriage.
