Not directly a peace festival per se, but knowing the crowd at these psy-trance festivals and parties (I used to go to a lot of them), most of them were peace loving misfits forgetting the hardships of life with music and ugh… stuff that makes you happy. I can’t think too long about these poor kids experiencing hell just before they died. There’s no excuse for this, no matter the context

A peace festival held in outskirts of a concentration camp, where people are getting massacred daily. Where children get separated from their parents or families daily, if not murdered themselves or burned alive or raped. Where people are given just enough electricity, drinking water and food to experience slow death and suffer.

Literally you have the entire world open, and if all the places to party and rave you choose that? It's pretty ironic to call it a peace festival.
