The thing you are ignoring is context of how content is presented, what a person expects, and how a person is generally expected to engage with the piece of media. Content in itself doesn't tell you anything whatsoever about philosophical things like what makes something morally good or bad in itself, or morally good or bad to derive your titillation from, morally good or bad to spring on people who probably had no expectation of it, etc. Furthermore, being morally acceptable or not is still yet another distinct issue from whether it is or ought to be socially acceptable.
I can tell no one here is thinking about these things (i.e. the fact that creating a pieces of media is a way of interacting with other human beings) but rather about rights and freedoms because they started acting like I was advocating censorship of the game by saying it was disgraceful to include this bit. Not everything is about rights and freedoms and your right and freedom to do something doesn't wholly validate it in every respect. A person can fart in the elevator with others and while that doesn't mean they need to be penalized nor that we should put up "No Farting" signs in elevators, it is still disgraceful.
Bringing up RapeLay as problematic would seem to indicate that at least one person here has some concept of what I am talking about. The rest is just extrapolating that to the rest of life and deciding what kind of standards you expect from media and yourself, what kind of cues you expect to know what you're getting into, and what you consider acceptable to be a surprise depending on this that or the other contextualization and narrative direction afterwards. If this was actually dealt with in a heartful and meaningful way afterwards to deal with the dark realities of rape and life afterwards through the characterization instead of just going back and killing the rapist, I might consider it groundbreaking and a step forward for the whole medium. Let me know if Arthur gets PTSD and nightmares, becomes hesitant in many things he was fine with before, has trouble being taken seriously and gets into arguments with friends, realizes the impact on him and finds ways to work through it.
The game is about them being on the run for their crimes and dealing with everything of their circumstances and the wild west context in meaningful and human ways like this, so why is something as serious and trust-breaking as rape an implied "it's just whatever" silence or unrealistically narrow "I'll kill him!" then life proceeds normally? It is minimizing in such a way that it's almost like we're meant to get some sick kicks from witnessing it and that's all.
