It's an irrational fear. Why would the government want to shoot you when it can put you out of action by suing you with pockets deeper than yours, tying you up in the courts and bankrupting you?
The fear did make sense - once upon a time - when weapons technology was so primitive that the government owned the same quality of musket that you did. Now they have stuff so dangerous that even the NRA wouldn't want you to be able to buy them. As far as force is concerned, you and your Sig Sauer wanting to take a brave stand against the military (or police) might of the national security state ... good luck to you .... and don't expect anything more than pious words from your fellow enthusiasts of liberty if you do take a stand or if the government does come for you. They won't be standing next to you or between you and the government (ask David Koresh). They'll be oozing sanctimony from a media platform a safe distance away. They might speak at your funeral but one thing they won't be doing is standing shoulder-to-shoulder with you against the armed agents of the state.
In any case, the rationale for bearing arms in case of potential tyranny died when Roe V Wade became the law of the land. What's the most important human right? The right to life. Are thousands of humans being murdered every year with the active or tacit assistance of the state? Yup. Is there tyranny happening now? If you're a foetus, yup. So, anyone in the NRA or the Tea Party or whoever raising a firearm against the government for violating this fundamental right? Nope. So there you go. This noble talk about packing a gun to defend liberty is horse manure, and has been so at least since 1973. After all, if you're not going to use your firearm now to protect an innocent child from being killed today, when are you going to use your firearm?
Guns are useful for practical things like protection against crime and for sport. But as a constitutional icon like the tablets on which the Ten Commandments were carved? Oh, puh-leeze.
It is an American thing, Roystan. You wouldn't understand it.
