I am probably wasting my time trying to talk sense to people who think they know more than other people.
First, not everyone has the same definition of the word "tyranny." Some conservatives view Obamacare as tyrannical while many liberals view it as not going far enough in terms of nationalized health care. Furthermore, a law or tax viewed as despotic by some citizens might also be regarded as a necessity by the government. In the late 1700s, some Americans viewed the Founders in the same manner that many of us view Bush or Obama. Whether it was anger of taxes in the Whiskey Rebellion, or unfair treatment of veterans in Shay's Rebellion, armed Americans have never been able to overthrow their government, even in the early years of the country.Simple fact: the Founders might have given citizens the right to bear arms, they viewed any rebellion to their authority as a mortal threat to the republic. Also, as Richard Brookhiser, the historian and senior editor at the National Review, states, it's the responsibility of citizens to vote or debate, not engage in violence in order to change legislation.
The real lesson here is that any illusion that owning one gun, or one hundred guns, would frighten or alter the way government behaves is not only unrealistic, but something George Washington would find unacceptable. The view propagated by the NRA that gun ownership keeps the federal government "in check" is not only historically inaccurate, but also contrary to the actions of our Founding Fathers.
