Actually I have a correction of the below:
>this idea that it's wrong to criticise people unless they ask for it can explain:
My correction is that the environments that cause killing and violence are not virtual reality environments, so they are not explanations and therefore not criticism, if my definition of explanations as kinds of virtual reality environments is used (one could alternatively call those VR environments "models of the world" and only call specific kinds of natural language expressions explanations).
Virtual reality environments are usually simplifications of non-virtual environments. Virtual reality environments (i.e. simulations of environments) have different hardware than the environments they simulate.
