> Weapons stopped Hitler. Weapons stopped USSR. Weapons stop US. Weapons stop todays Russia. That's just a rephrasing of the same old "good guy with a gun" meme.
Anything wrong with that? Think: if you try to remove all guns overnight the ones you get is the ones from the good guys. If you make guns illegal only criminals will have guns. Also: the biggest crimes against humanity have typically been made by the local rulers: Hitler can be discussed, Stalin, Pol Pot and a number of others cannot.
Good guy with a gun tends to hit a bystander, or cause dangerous escalation in situations that don't warrant it, or have their gun stolen.
> If you make guns illegal only criminals will have guns.
That's one way to look at the very short term. But then since "criminal" is not an immutable quality of a person, millions of people that weren't criminals that then commit a crime will have no gun.
Trying to sort people into "good guys" and "bad guys" is a terrible idea in general.
