All I'm reading in what you wrote is excuses and double-standards.
Y'do realize that there aren't any real people in this game, right? Or any other 2DCG game of this type?
Technically, by your logic, anyone getting off to oddly proportionate drawings that don't actually resemble people in a real sense have mental issues. The fuck's wrong with those people, fapping to some drawings with weird anatomy when they could at least find proper porn with real women in it? Right?
...
Now... if those people you're talking about were looking for, y'know, porn with actual people involving the subjects involved in this game... then yes, I'd absolutely agree that they have some serious issues. And don't pretend that such things don't exist. Scat porn absolutely exists, and as far as I know, it's not even particularly illegal, just extremely unsanitary. The gore stuff though is obviously illegal, but we all know that fucked up people exist...
Take your kink-shaming shite out. You're just another one of those people that wants to pretend to be morally superior just because they claim they don't like a more morally objectionable kink.
Hell, isn't kink-shaming against site rules? Isn't saying that people with certain kinks have mental issues a definitely clear form of kink-shaming?
