I think that gore is an easy scapegoat because this allows us to shy away from the difficult discussions. "We should ban porn" occupies the bandwidth of social discourse, and therefore we cannot discuss topics like "ok but really, what do we do about the demographic collapse". I honestly think that the kids growing up now are going to be much more traumatized by the fact that they'll find themselves in a world of insane wealth inequality while needing to support an army of retirees, rather than seeing a pic of a dead body.

BTW seeing death, disease, and misery was completely normal through entire human history. We live in abnormally safe times. Maybe there is some mechanism akin to allergies, where immune system cannot believe that everything is chill so it overreacts to tiniest threats.
