“[T]here is a difference between lions and asses; and he is a fool who knows not that swords were given to men, that none might be slaves, but such as know not how to use them.”

A well regulated (armed) militia needs be sufficient in the tools of their trade

"That none might be slaves" No unarmed society has ever been a free society. Know guns, know freedom. No guns, no freedom.

We have updated the quote to put it in context, as the previous version was grammatically incorrect. Thanks.

Slaves are never permitted the means to defend themselves against their masters.
