Isn't it funny how everyone who imagines this kind of dystopian revenge fantasy imagines themselves as the victorious overthrowers, rather than the overthrown or as those who get caught in the middle?
The truth is that the vast majority of those who think in these terms are too busy playing their dystopian video games to actually do anything.
The few wingnuts who do actually try to act usually just end up shooting up their school, place of employment, or whatever, and either end up in prison or shooting themselves.
The ones who post about it online at least provide a clue as to their intentions, increasing the probability that they will be stopped.
