I don't think you get to decide what is and isn't okay for a child. That's a decision the child's parent gets to make. We really need to stop coddling children as if they're these weak and flimsy things that can't handle video game conflict. They should be exposed to these kind of things alongside supervision, so that they can develop properly. Reporting people for acting in a way you disapprove of is fairly immature, and we should report you for that transgression. You need to grow up.
