How Old Do You Have To Be To Defend Yourself?

So how is it that the Left thinks self-defense is something that you shouldn’t consider before the age of 21? Police: 2 teen girls shoot teen boy in self-defense during fight at Perry home.

[Captain Heath] Dykes said police believe the girls got into a fight with the boy, adding that it appeared the shooting happened when one of the girls pulled the boy off of the other girl, took the gun, and shot the boy in self-defense, Dykes said.

All this is still under investigation, and the attacker was still in surgery. (He has multiple gunshot wounds.) But self-defense is still a human-right.
