I have visited the USA on many occasions and always felt safe. You would more likely be killed in a RTA here than in gun crime there as a visitor. So it’s a tiny tiny risk.
However, Americans don’t trust each other. South Africans don’t trust each other either. They keep guns to protect themselves. I think they are mad but, having talked to gun owners in the USA, they really see it as the ultimate self defence. The biggest issue is what guns they own, how many, and mental health. They do see gun ownership as a right snd usa politics isn’t set up to change anything.
I also find it odd that people who worship God, in the Bible Belt for example, have no qualms about killing people. It seems very Old Testament. It’s not a world I inhabit or even understand. It comes down to being scared. Society there needs to change to remove this and reduce gun ownership,. Removing certain guns from sale would be a start but they will still circulate!
