If there's one thing that's sorely needed right the fuck now, it's teaching kids how not to be a fuckwad on the internet. The earlier, the better. Hell, I remember even in 2004 we were effectively taught this exact concept as part of I believe it was design and technology class. Naturally, it focused almost exclusively on email, since back then social media was non-existent and everyone over the age of 25 thought forums and chatrooms were the exclusive domain of paedophiles and FBI agents, but the spirit of it was largely the same.
I for one applaud this teacher.
