In this case, there is no question how 8 of the 9 will decide (4 for homosexual marriage and 4 against), so the Constitution says whatever Kennedy says it says. Be afraid. Be very afraid.
At this point the Supreme court has made so many rulings that are manifestly insane, that they have effectively surrendered their legitimacy as an interpretive body.
They can rule it, and even the states can accept it, but the one thing that they cannot do, is make me accept it. And I will not.
Sodomites do not reproduce, they recruit. You are not born that way, you are lured that way. There is no right to marry, even a man and a woman, enshrined in the constitution. That is a matter of law, church doctrines not withstanding. Change the law but using the courts to force this on an unaccepting populace is the way to destroy your moral authority.
