You would be correct. I believe it took several Frigates to conquer the Barbary Pirates.
I believe the 2A refers to "arms" as any means of defence for your personal protection and which could be used to overthrow a Tyranical government.
Am I wrong?
I guess it depends on what you believe can be used to overthrow! ;-)
My gut reaction - no, you are not wrong.
But I'm afraid you think we could use just our firearms to actually overthrow a gov!
BTW, no disrespect meant here. Partly I'm getting confused as to who said what! Always good to find another RevWar "fan"!
Any and all writings we have on the subject left for us by the Founders indicate that the 2nd was meant to protect us from the government they had just formed. These men realized that any government has the propensity to become tyrannical if left unchecked.
One Founding Father was even quoted as saying that the 2nd Amendment was the guarantor of the other rights that God had granted us.
And you are quite correct in saying it was frigates that took out the Barbary pirates. Specifically, it was the US Marine Corps and the US Navy, not privateers. A little swivel gun was mainly for sweeping the decks of an attacking ship, not for any actual damage to the opposing vessel itself.
