ARs and Cattle Cars

Those who wield the former are less likely to be forced into the latter.

Orwellianisms come naturally to totalitarians. Arbeit macht frei reads the inscription over the Auschwitz concentration camp.  "Work makes one free." So you are most truly free when you are worked to death as a slave.

The unarmed man is a defensively naked man.

Now I defend your right to go around (defensively) naked, but only on condition that you defend, or at least not interfere with, my right to go around 'clothed.'

Paraphrasing Machiavelli: Why should a man who is wrong pay any attention at all to a man who is right, and not armed?

Just so. In the world as it is, appeals to what is right carry no weight unless backed by might.  Suppose you are hiking in the wild. You come across a girl being raped by some brute. If you are unarmed, all you can do is appeal to the brute's conscience. "Sir, don't you see that what you are doing is both morally and legally impermissible? Please stop!" If, on the other hand, you are armed, then then you have the means to intervene effectively should you decide to do so. Whether you should intervene is a difficult decision that depends on the exact circumstances. I am making just one very simple and indisputable point: an unarmed man lacks the means to defend himself or anyone else.
