Absolutely not. Guns "democratize" violence. People who are less strong will at least have a fighting chance to defend themselves. Without guns, those with brute force have all the power. It would be especially bad for women.
When we have a country where everyone gets along and trusts the police and government, then we can have a discussion about banning guns. I still won't support it but at least you have some justification for considering gun control.
