What We're up Against
Have fun in your little made-up universe where the government comes to round you up and you manage to fight it off.
In the real world, fascism is when the corporations and governments work as a single entity, and you can wander around with your fucking gun all you want. In fact, you'll have to wander around, because the government/corporations took your house and your car, and no one will hire you.
At which point you'll be arrested, not as some big anti-government hero by jackboot thugs, but for stealing bread to live on, by a perfectly normal cop who's just doing his job, a job that absolutely no one except you disagrees with, so when you shoot and kill him you're getting the electric chair and no one thinks you're a hero at all.
There are different types of totalitarian governments, and assuming a fascist one operates like a communist one is faulty. Fascist governments don't put troops in the streets...they work with corporations to make sure 'the wrong sort of people' do not have any economic power, and do not have anywhere to peddle their ideas.
Modern fascist states don't even bother to kill those people, and pretending they're going to show up in some stormtrooper outfit and start a gun battle with you is insane. They'll show up with a court order to evict you from your home because you failed to pay your mortgage, because pressure came from the top at your company to let you go. Or they'll just sue you and ruin your finances.
America is not a bunch of tiny castles where, as long as you can hold off the invading armies, you will be fine. The idea that that is how the world works is astonishingly naive. Almost all the population of America lives in housing they do not fully own, they get food from places they do not control like the supermarket, they require operating in society for money to obtain said food and shelter, a society where economics are controlled by some very large players that can crush them like bugs.
And a fascist state isn't going to 'assume control', you asshat. There's not going to some insane coup, there's a going to be a slow change, which has, in fact, already happened, or have you not looked at the telecom immunity stuff? That's classic fascism. The government breaks the law, the government gets private companies to break the law, the government gives said companies huge amounts of cash, the government attempts to make such behavior legal retroactively. We've got government officials and AT&T officers leaping back and forth between each other in an incestuous loop. Your government spying on you, sponsored by AT&T. It's not 'totalitarian' yet, as evidenced by the fact Democrats managed to stop the immunity, but it is fascism, at least the start of it. (And the same thing's happened with Blackwater.)
Oh, and before you start ranting about gun control some more, be forewarned I'm against it. I'm just not stupid enough to think that the US government being slowly corrupted by business is something that can be fought off with gunpowder. Guns are useful to deter crime and to deter invasion. They aren't useful against a corrupt government in any meaningful way...source
