Doubt most of us Americans are thinking of "overthrowing the government". We just don't want to be at the mercy of a dictatorial, Lefty tyrant.
"When the government fears the people, there is liberty. When the people fear the government, there is tyranny". This is what American gun ownership is mostly about....that and the right/ability to possibly defend one's self/family from criminals.
Hehe, there is only one authoritarian in power right now. Remember when all the predictions were Obama would cancel the elections

And they will use poison gas or biological agents. In for a penny, in for a pound at that stage.
