I guess we're just debating semantics. I don't disagree with your assessment of the practical implications. Just the conceptual assertion that everything passed by Congress is, by default, "Constitutional". It's perfectly valid for a citizen to believe that a law is unconstitutional and act on that belief. Obviously, that's a gamble. They're still going to be prosecuted, and if they Court doesn't agree with them, they're screwed.
I guess I'm just responding to your statement as a common retort from statists, when someone claims a law is unconstitutional. They're basically just saying "sit down and shut up", and I don't brook that. If you think government is out of line,
it's your responsibility as a citizen to call bullshit on it and challenge it, in court, on message boards, or wherever. Maybe not on Facebook or family meals. But....
