My answer to when? is;
Not Now and not Never. I have not been able to narrow it down much more than that yet!
For me one way to say what has made this country great and unique is its foundation on Individual Liberty which can also be called Individual Responsibility.
So I reframe your question into: At what point does my commitment to Individual Responsibility cause me to choose to revolt and bring down the govt?
I think a more realistic scenario is succession of a state or states (say Utah, Nevada, Arizona) into a liberty zone. I would join at least until the pols and lawyers screwed it up!
Target rich post, thank you. Individual Responsibility was never an easy task, nor should it be. The problem with society today is that it is very easy to "coast", watching MNF, drinking beer, paying taxes, shuttling kids here and there and cursing politicians for their actions or in-actions but never doing ANYTHING about it.
Succession has been tried and the result was the BLOODIEST war fought on US soil, the one and only Civil War. Our country is broken, the rules are not being followed and no one, NO ONE, is questioning the actions of the powers that be. Do you realize that two of the first Supreme Court justices were removed from their posts for being drunk in PRIVATE and for cursing? We are so far off course it will either take a long haul-gentle-course correction or and immediate hard right. Neither of which seems to be supported by either political party.
The day will come, it WILL come, when you will have the choice to resist or register/turn in your guns. If not you, your children. It sucks I know, no one wants to think it is even possible let alone likely that our .gov will force us to armed resistance- there is a term "Normaliy Bias" that is applicable here, that is it causes people to underestimate both the possibility of a disaster occurring and its possible effects.
