One of the mental hurdles we will have to get people over is this idea that just because the superficial trappings of representative, elected government are still used for ornamentation doesn't mean this is not a developing tyranny, and it doesn't mean we will somehow be anything less than righteous when we are finally forced to confront it openly.
"They're just doing what the people elected them to do", "If you have a problem with how things are, you can seek redress from your elected representatives", "We had free and fair elections (barf) and they won", and various permutations of this line of reasoning are going to have to be addressed. The first line of attack I take is the fact that this government was instituted to acknowledge and protect our fundamental, natural rights. It is not itself the progenitor of rights, and therefore it is not the prerogative of the state or any number of useful idiots to decide upon the disposition of these rights. Second, I would argue that the process itself has been corrupted beyond hope of repair. Our Founders implemented thoroughly brilliant failsafes into our system of government, making its various branches quite deliberately adversarial in nature. It is a testament to the Founders' genius that it has taken 200+ years for demagogues and would-be tyrants to short circuit their checks, balances, and safeties -- but it has nevertheless happened and we must recognize it.
I think this is worthy of a discussion thread in itself, this discussion of how to counter the phony legitimacy of government. Just imagine you are talking to the average middle of the road person (i.e. not a confirmed moonbat), how would you counter them when they raise objections such as "Well, come on, we still have elections" and "I don't like it either, but this is what the people decided" (as an aside, this demigod status that gets assigned to "the people" is like nails on a chalkboard) and various other appeals to the hollowed-out leftovers of a once-representative form of government?
