This assumes that people will blindly follow these unconstitutional orders. This type of situation is the exact thing that will cause violence, civil unrest or even another civil war. IM2, you sit back as if this would be some type of victory for leftists. However, this would only be the tipping of the scale for a gov't to no longer fear the people. Then, when there is no one to fight back against tyranny, and the gov't then goes after you, for whatever the reason, race, religion, because you're just dumb, then what will you do? Pull out the little .22 you were hiding hoping it will stop the coming onslaught? Good luck.
And don't even begin to think that such events couldn't happen. If you can't say that the gov't will never become tyrannical, than the people should have the capacity to fight that tyranny. That is why the 2A should NEVER be a divisive political tool. Unfortunately the left love their 'god', the government, so much so, they will forget history and the atrocities of gov'ts that have disarmed their population to the only mass murder so many of them. I hope you understand, that is the type of future you're potentially allowing to happen.
