That’s like saying “No one has died from alcohol. Their body killed them”
Guns have no direct influence on people’s behavior. It doesn’t cause you to go to sleep or reduce your reaction time or want to go to Taco Bell. Alcohol and weed do.
The cause of death for a drunk driver who kills himself is “auto accident”, not “alcohol overdose”.
The political goal-seeking you are engaged in right now is a characteristic of the far left. And as I have no patience for dishonest debaters, concede the self-evident fact above or consider this discussion over.
