Are you the parent of, do you have friends who are, have you ever been–a teenager? Teenagers are bullied, they are angry, they have unhealthy interests. This is not to say that this is therefore normal and should not concern anyone. This is saying that teenagers everywhere feel, suffer, struggle. And they need more help than we currently give them.
Yet America has disproportionally high incidence of gun violence, and that includes school shootings. Why do you think that is? Of course it wouldn’t have anything to do with easy access to firearms. Of course it wouldn’t have anything to do with the heroisation of the military, with the number of war veterans, with a culture of firearm fetishism. And it certainly wouldn’t have anything to do with the normalisation of firearms in cinema and on TV.
No, instead of focussing and directing attention and effort toward the source of the problem, you want to now blame the fellow teenagers who are trying to make their own shitty way through their own shitty lives?
