My knowledge of constitutional law, where do you find it lacking?
When Orval Faubus, the governor of Arkansa, refused to integrate a Little Rock public school in 1957, defying the Supreme Court's ruling in Brown v. Board of Education, President Eisenhower sent troops from the 101st Airborne to Little Rock to enforce the law. I doubt this president would do anything like that, if the Court were to concoct a constitutional right to homosexual marriage, and one or more of those states refused to amend its law to recognize that "right."
It is exactly because the Supreme Court has no power to enforce its decisions that it is so important those decisions be worthy of respect, rather than being nothing more than expressions of the personal views of a handful of judges. That's just what Roe v. Wade was forty years ago, a concocted decision that deserved no respect--and yet every state changed its laws to comply with it. It would be interesting to see if that is still how things are, or if any state is willing to engage in nullification.
It all boils down to rights.
Some people seem to think that because someone has rights to something they disagree with, then they are violating their rights, or its a war on their religion. Guess what? Just because you dont agree with it, doesnt mean they dont have the same rights as you.
