Separating fiction from reality

Sometimes I come across them proshipers or whatever they're called and they say that all the time. They apparently separate themself from fiction so hard that they dont feel uncomfortable by a graphic depiction of some little kid getting raped by their dad,
But I dont get it how that works, like obviously this fictional scenario isnt real and the manga characters aren't real either but you're real and the thing the manga is depicting happens in real life.

I know most of y'all are woke like me help I need you to agree with me because I feel like thats crazy
