It's dumb and it's there to pander to an edgy audience, but it really shouldn't be a problem. Why does that scene bother you? Isn't it just because that stuff is taboo?
So if some of us like watching people peeing on each other should we all be sent to Gulags?
At which point is the line drawn?
B) Some people can feel elevated disgust towards portrayals of other people being sexual. In that case, the fact that it's sexual does make the difference, but it's still a disgust reaction.
1. It insults the intelligence of the viewer and indicates the rest of the show will do the same
2. Humans urinating on each other combined with torture is disgusting to the vast majority of viewers, and seeing a scene like that will naturally turn off many viewers. Even Game of Thrones saved the rape?-on-top-of-a-corpse scene for after the characters had substantial development.
On a related note, at what point does "don't judge" end? What if the opening scene depicted necrophilia? How about beastiality? There's nothing wrong with being disgusted by things 99.X% of the planet is disgusted by
Or consider that the intent of that scene was to inspire disgust in the viewer. Does it tie into character development somehow?
Also, don't kink-shame...
Volenti non fit injuria. Necrophilia is ok, beastiality not so. Easy.
(Not that I'd like to see either, just saying which would make me search for torches and pitchforks.)
