Is this not morally repugnent?

I never understood why users on this website get so much hate, until I got in this argument. I'm currently in a huge argument with someone because I said that making r34 of minors, fictional or not, is disgusting and gross. They continue to say I'm just an incel and whatnot. Am I going crazy or is this genuinely awful??? They're literally willing to die on that hill. They continue to argue that r34 of minors is morally decent if they're fictional. Like... NO?!
