Guns are not the cause of violence, husbands that come home early are.
No but for real, if guns never existed then people would just do harm with another weapon.
Think about your statement in another way, instead of "less guns equal less violence"
What if somebody said "less penis's would equal less rape" , rape would still exist and so would violence without guns.
Guns are not the leading cause of violence, in order for your statement to be common sense a gun would have to be the 100% only way a human could be killed,BUT in reality anything and everything is essentially a weapon , in order to put a stop to violence every single human being would have to be in its own separate cage
