It is because of the kind of government that the British imposed on the colonists that brought the Declaration of Independence and the Bill of Rights into being. It was even then a hard fight to get all the colonies to agree to it.
Nothing to be scared of? Think man! Look at what happened to Germany, Russia, Italy, Poland... Need I go on? No one believed it could happen in their country either. But it happened! And, it can still happen even here in America. Count the number of communists (socialists) in our government today, even within the Administration. We are closer to losing our freedoms by our own government than any generation before us.
I understand your concern.
In a roundabout way, I'm trying to say, "Buck up. They can only take our freedoms if we let them. 's why we have guns--to fight back. Just get over being scared; move into being angry and ready to fight back. The guns aren't intended to be a deterrent. They're intended to be used."
Its gonna happen, meaning the tyranny will deepen. Jefferson made three remarks--the tree of liberty needing to be refreshed, hoping we didn't go twenty years without an insurrection, and the natural course is for government to grow and freedom to shrink. We also have that other (historian?) (philospher?) who laid out a progression from freedom, to decay, to tyranny (with other points in between.)
The tyranny guys are gonna keep grabbing for more. They're just gonna keep trying. They're not going to stop. For example, even as we trade posts, Congress is pushing through a $1.2T spending bill. One point two trillion. In the midst of a very deep recession. In the midst of all their so-called concern about the national debt. (If Congress and the Federal Reserve aren't national security threats, nothing is.) In the middle of the mess we're in, despite their pious noises to the contrary, they are still playing the business-as-usual game. One point two f__king
trillion.
I'll admit, it is not inevitable that tyranny arises. It is possible to stop it before bloodshed. But, I don't see it as being likely.
So, the question becomes, "What will I do when it arrives?" And, "How will I know it has arrived?"
