Wrong…if you studied actual self defense with guns you would know you are wrong. Guns give the weak an equal chance at causing harm to the strong….the attacker then has to make the decision on wether to press the attack and risk death or injury or go and find another, unarmed democrat to rob.
Guns give you a decent chance kill those without guns, nothing more. If everyone in the fight has a gun, the odds are no longer in your favor.
If given the chance to be stabbed versus shot, go with the knife. You are much more likely to live.
