There is an argument to make. The Second Amendment is there to protect the people against all enemies: foreign and domestic. If the Second Amendment is repealed, abridged, modified or otherwise tampered with, it weakens the nation against those enemies.
You can spout all the hyperbole you want, it doesn't change the reality of the situation: that if all other rights are taken from us, by stupidity or surrender, the Second Amendment is the last line before Americans start getting herded into railroad cars.
And that's not going to happen on my watch.
That clear enough for you, or do I need to use charts and graphs and an easel?
