The Bill of Rights (first 10 amendments) was ratified effective December 15, 1791.
The Second Amendment says “The right of the people to keep and bear arms shall not be infringed.” It doesn’t say the opposite. It doesn’t say, “except if socialists oppose this amendment.” It doesn’t say, “unless Congress or a federal judge disagree”.
The founders saw fit to spell out this right in the Second Amendment, so obviously it was in the front of their brains..... a priority. Every dictator in history has stripped the citizens of their weapons, for obvious reasons. The founders knew a great deal about tyranny. They knew that citizens must have weapons with which to defend themselves against the tyranny of King George III, and they wisely foresaw Stalin, Hitler, Mao, Castro, Saddam Hussein, the Kims of North Korea, FDR, and Obama.
