How about, stop trying to assert your manhood like every other 14 year old does by bashing on the gays, or are you compensating for something? Your opinion of morality isn't absolute, sorry to break it to ya.
Is it possible there will be more cases like Iowa where the courts force the change?
It's getting less and less likely. Of the states that don't have amendments, a few have already been to the court and have lost, and it would take a new composition of their courts and some years to even try again... it'd be weird for the same people to go against their own precedent just a few years later.
New Jersey is worth looking at, though. They said to make same-sex couples equal a few years ago, and the legislature went for civil unions. They tried doing marriage late last year, didn't make it, and even in the debate, everyone was saying civil unions weren't equal, even some opponents. So, it's going back to the Supreme Court. But I don't know anything about Jersey courts to comment -- I guess they have good points if they use their opponents words against them. And the case is being argued by the same people who got same-sex marriage in Iowa.
