The need for guns to protect yourself I guess depends on what country you live in. For example in Sweden the changes of getting murder is 1 to 100 000 and 1 to 400 000 if you are a lawabading citizen. So they are no need for having a gun to protect yourself from getting murded.
Then you look at males it also clear that they should have no guns to protect themself in Sweden. Because the most common reason for us lawabading male sweds to get a beating is in a drunk fight. And you should never have guns around i a drunk fight.
Then it comes to females yes their are the risk of rape. But their you also have other option like sprays, alarms etc. It can be really intersting to see statistic on what protective methods is most effective. The problem with guns is if they go of during the fight, then the female can be killed.
