Repeal the second amendment, confiscate all privately-owned firearms, improson anyone who resists.
Precisely why we need the 2nd Amendment ^^^.
I'm opposed to this kind of thinking^^ about the 2nd Amendment: that people need guns to be able to shoot at government officials who intend to confiscate their guns. If all three branches of the federal government have decided to ignore the 2nd Amendment and confiscate guns, the right way to react to is comply, not rebel and get violent. I think it was Abe Lincoln who said that in a democracy there is no successful appeal from the ballot to the bullet.
You stated the issue exactly right, but came to the wrong conclusion. When government ignores and abuses the rights of its citizens, that is when the citizenry has a duty to resist. It was Thomas Jefferson who wrote on how the people should respond when government engages in this kind of abuse, saying "it is their right, it is their duty, to throw off such government".
