And it was far from the only thing of that sort that happened. I remember really upsetting people on a couple of occasions because I thought about the likely, harmless consequence of what I was saying, and didn't consider whether it could cut some people much deeper.

None of us were taught to do this by gaming online. Honestly, I'm doubtful that gaming teaches cruelty any more than team sports or school cafeterias do. I get that it's depersonalizing and people say cruel things, but it feels like a boogeyman given how much actual violence gets ignored at that age.
