Gay Marriage & Romantic Love

I can't help but wonder if anyone has ever written about how, if those against gay marriage continue to have their way, the "conservative" notion that gays are welcome to marriage all they want as long as they marry straights is tantamount to denying gays a marriage defined by "love".

As you may be aware long ago marriages were decided predominantly by familial political and/or fiduciary criteria. Eventually in Europe the notion of a romantic love was born. Today in most modern societies the notion of a marriage based upon love is considered to be normal. But not for gays; today, if a homosexual or lesbian choose to be married in most modern societies, they must marry for political or fiduciary criteria.
