The advocacy of a political end cannot be separated from the advocacy the means it is brought about. The case in this point is that the disarming of The People requires the use of deadly force. Some advocates of "Gun Control" do not have a problem with this. In their view reality is subject to a vote and therefore a vote to legalize the murder of citizens who own guns is morally correct.
But Reality is Real. Reality is not subject to a vote. And Murder is Murder. No vote by any political body can change that.
The advocacy of "Gun Control" is the advocacy of Murder. A government that legalizes Murder in this respect ceases to be a government and devolves to a gang of criminals. And as such it must be put down by deadly force.
And those who pushed and voted for the Murder of gun owners must themselves be put to death.
