I think (from what I'm hearing anyway) is that one of the big complaints on Goblin Slayer was that it was mislabeled by streaming services as being rated PG, and that people were caught off guard when it was decidedly *not*.
I think it's more along the lines of "If you took everything out of the show that's definitely NOT rated PG or below, or made the stuff PG, you're left with a really dumb manga/show that isn't worth reading/watching."
And that doesn't have to be true. It's just lazy writing.
The novel I mentioned a few pages back ("JK Haru is a Sex Worker in Another World") would still be an engrossing read if you took a black Sharpie to every single line of her 'sex' scenes. She's sassy, pissed off that she's trapped in a gross otaku male fantasy world, and just trying to get by as best she can in literally the ONLY way she can.
Or take an oldie, Claymore (because I don't want to bring up Berserk/AoT again). If you made the whole thing PG, you're still left with an interesting story about women who have to save the world from demons by BECOMING demons - at least partly - and how they deal with the rejection of the ordinary human world and the lure of going over the line entirely to demonhood.
EDIT: I do want to make it clear though: If you like it, that's FINE. Everyone wants some gratuity sometimes. But we aren't complaining because it has violence and rape - we're complaining because if you take that away, Goblin Slayer isn't much of anything else.
