Well sure there are plenty of things that need interpretation, but interpretation =/= making things up out of your rear.
For instance, the Bible is meant to be interpreted obviously, and you believe in the Bible doesn't mean that you think a Beast is going to come out of the sea literally. However, you can't just make stuff up, there needs to be a viable interpretation.
The Second Amendment can literally mean nothing else other than "You have the right to keep and bear arms" anything else is making stuff up. The tenth amendment clearly says "If it doesn't tell the Feds they can do it, they can't." There's no other way to take those. If SCOTUS can't handle that, then maybe states should start seceding and taking up arms again, and prove to them that making crap up doesn't make it true.
Secession is legal according to Constitutional law. SCOTUS rambling and using judicial activism doesn't change that.
@Lighthearter- The North wasn't fair to blacks either, and the Confederacy wasn't oppressive to white males. If it was an invasion to liberate the slaves, and not for power, I'd support it. I am glad it happened BECAUSE it freed the slaves, but that doesn't make me support the North's actions. I am glad Rome persecuted Christians because it allowed Christendom to grow, but that doesn't mean I approve of their actions.
As for the Communist government, if they allowed us to leave, and we refused, they would be within their rights to attack.
Also, I'm fairly certain that annexing territories by military force to make them into states is illegal.
