From reading this insane wall of text, it is clear that the only true 'issue' that you have against the game as a whole is the concept that scenes of CNC are represented at all, let alone explored in a FICTIONAL setting.
I, myself, have been in this exact situation and have been in a worst-case scenario just like these themes here. And trust me when I say this: This creator handled the subject of the topic better than any other source of visual novel media than anyone else I have known, let alone seen, explored this heavily in a way that still respects the very topic.
And you saying that the creator didn't do people like me justice and rant about how it is represented poorly on those that practice CNC is a HUGE insult to actual to me, as well as others that also see what the creator had achieved.
You state that the creator has insulted you and the very idea of the content that is provided and warned at nearly every angle before you even play, and that they have poorly labelled anything that you have stated within your line of dialogue.
I would like to remind you that they have labels for a reason and that it is repeatedly shown to you that the setting is FICTIONAL and that they, themselves, DO NOT CONDONE the acts that are portrayed in the game.
Clearly, you did not take the 'Player Discretion is advised' seriously and chose to get your own
ego and what is left of your pride, of the themes this utterly wounded, rather than take it with a grain of salt and just enjoy the goal the game has clearly achieved. And that alone tells me that you do not hold even an ember of understanding in critical thinking and use the offence of your own emotions as a shield to avoid your own problems, rather than face them head-on.
Furthermore, there is 0 concept of anything racial being mentioned throughout the entire game as a whole, nor was there even a hint of anything remotely suggesting that POC are even being a sole focus for these things to be explored at all.
If anything, YOU even bringing it up as a counterargument tells me more about your lack of moral code of anything that is outside of your clearly biased ordeals of the manner and use it as another shield behind a computer screen, where you know you can play 'keyboard warrior' instead of using critical reading analysis to fully grasp the ONE SHOT novel of story that is of the character involved with Y/N.
And as a fellow writer AND artist that like to also explore these taboo topics on my own time and have a clear understanding of why these themes are considered taboo in the first place: You have missed the point entirely and are trying to just pick a fight with someone who is clearly more level-headed and more in the know of why these topics NEED to be explored in other mediums so that a more REASONABLE discussion of said topics can be better represented and better understood of how one COULD handle it.
It is not the creator's responsibility to cater to you, nor is it yours to give out highly inaccurate advice of what you deemed ideal, because, one more, YOU decided to get yourself hurt after KNOWING what the topics hold in detail.
Please, maybe do us all a favour, and just do not interact with something that is going to clearly bruise what is left of your already beaten down existence and compile yourself better in knowing YOUR boundaries over complaining that it was crossed by your OWN actions to a person that holds no responsibility of YOUR actions and reactions to these things and maybe, just MAYBE, actually find someone that have been in participation of these themes to expand your data base of being less bias.
Sincerely, A 10-time survivor of Rape Victim and explorer of Taboo Kinks of media like this.
