I would suggest a reading on the subject of the Warsaw Ghetto uprising in 1943.
When you read about the Polish Resistance's weak support and lack of supplying weapons and ammunition, it becomes very clear - if you can't take care of yourself as a people, then others who can and will exercise a program of euthanasia will attempt it.
This has happened repeatedly in human history. It is exactly what the British first attempted in controlling their colonies here - they arranged to safeguard the Boston Militia's firearms, and then simply walked away with the keys. Being disarmed, the city had no choice but to comply, and the British obliged themself by quartering their troops in the people's homes. There were no barracks or military facilities.
That meant knowing that when left the house for work, you were leaving two or three lonely, armed men at your home - with your wife and daughters. Not that they didn't have duties to perform, but since they lived in your house, it was up to you to put up with it. Feed them, too.
There were some ways to complain about their behavior, but after months of close proximity, even the most polite troops could finally succumb to their natural impulses and their intent be clear: Men will be men.
Since similar instances have continued to reoccur in history, in this hemisphere and around the world, you find that other peoples sometimes look to American with it's Bill of Rights as being where they would prefer to live. And they do anything to get here.
Ask around in your family, neighborhood, and friends. Unless you find someone who is Native American, ALL of our ancestors moved here to escape the oppression of their home country. Mandatory service in the Army, taxation, extremely limited opportunity, on and on - our forefathers, whether from England, India, or Italy, all wanted to get out from under the onerous conditions of their nations and move here.
One reason - the 1st Amendment, which they quickly learned was genuine. They actually could voice their opinion, and they actually could win political arguments and even in court. We as a nation have a higher law than the overseers word. Even they are supposed to adhere to the systems of government.
That 1st Amendment exists in our bylaws entirely because of the 2d. If you can't literally defend your rights from those who would oppress you, and meet them with equal resolution, they will run you over and trample your rights.
LOOK TO THE WARSAW GHETTO UPRISING. They held on as long as they could, but in the end, they simply couldn't stop the Nazi's from literally herding them in trucks and driving them off to the gas chambers of Treblinka. The Nazi's demolished the Warsaw Synagogue with explosives, and literally erased the lives of tens of thousands.
With that lesson purchased at such a high price in Jewish blood, I find it incomprehensible why so many of Jewish origins don't own guns - especially when their brothers and sisters in Israel carry them on a daily basis for the exact same reasons the Ghetto needed them. Be armed or be killed.
I don't question those of faith who choose the tenets of being a non combatant. Please don't question my right to combat those who would take away my life, my family, or my faith. We are not all chosen to be martyrs. In America, we have the right to oppose those who would violate the basic right - the right to live.
Those who would oppress us chip away at our rights, and the last American left standing will likely have a gun in his hands. They will pay a high price to pry it from his cold dead hands. Better that, than a long ride in a cold truck to be stripped and thrown in a ditch. Many in Warsaw made that choice.
Tyranny hasn't stopped, it just chooses the easiest prey.
