Obviously society is broken, and guns are doing a lot of the breaking. The people teaching these classes agree about that as well. But they’re not in a position to fix that. They’re trying to use the skills they have to mitigate one part of the fuckedness. Maybe two parts: a kindergartner could perhaps save their friend’s life one day, and in the meantime they’re already having justified nightmares about shootings, so maybe the lesson will let them turn those dreamstories in a slightly better direction.
Cringing means you’re better now than you were then.
Besides, after seeing the debate, the sense of doom is going to keep me up all night anyway.
