What sort of civilized country accepts this?

Some how kids are not learning personal responsibility and morals. Is public education system to blame? Or music/TV/movies/video games? Or declining religious participation? Or lack of parental involvement?

Kids in other developed countries also face the same challenges, but not having guns in their homes and neighborhoods means that they don't face the same risk of gun death.

"Includes suicides"

So, do you want people to actually kill themselves, or attempt and get help? Because the presence or absence of a gun in the home is very often the difference between those two scenarios.

Really, it's the same math as "But you can kill someone WITHOUT A GUN": having a gun around changes the impact of someone's suicidal/homicidal intent. People are going to get angry or depressed, but guns are really powerful at turning those (temporary) states into PERMANENT deaths.

This is a harm reduction way of looking at the issue, not a moral one, but less harm is something that I imagine we all want.
