Wow. You are making an argument irrelevant to the point under discussion, which I made in my first post above, about the consquences of a political minority getting things the majority is opposed to, via the Supreme Court.
To get back to that, we have lived with the NFA since 1934. Tyranny has not descended; indeed, it seems like people who believe as you do are currently in the driver's seat when it comes to gun legislation, and have been for some time. Therefore, why the need to push on repealing the NFA? It might cause a backlash that would be harmful to your cause.
