You're absolutely fine! I broadly agree with what you're saying, so when I say the things I say next I want you to know that I'm speaking regarding my own personal feelings and not as much how I feel on principle.
I definitely agree that people shouldn't be bound by typical story rules (like I don't believe every movie should be a standard tropey superhero movie lol) but even in existing stories that are bleak, there's a purpose for that bleakness that couldn't be achieved if they weren't bleak.
I guess I just wonder why say, someone would write a story where you follow a villain protagonist who tortures random people who aren't even also bad people, they're just random people living their lives, and you treat what the villain does as cool basically universally and there's never an implication of any kind of comeuppance or even internal conflict or torment. It kinda feels as if that is something that falls under the initial posts' ideas.
I swear I'm not trying to strawman you or OP's post, this is genuinely me trying to understand it. Maybe I'm misunderstanding and the point of the initial post isn't that all the stories produced under this criteria would be quality/good, and just that we shouldn't try and micromanage people because it just opens up a bunch of other kinds of censorship and it just generally doesn't work.
However, I feel as if even with this framework, I would think it'd be justified if there was some kind of public outcry, not anything systemic just general populace, over a story that basically fits the description I said above. As in a story that more or less showcases someone terrible, shows it to be terrible, while also more or less romanticizing it and never adding any sort of nuance to themes or anything like that. I'm not saying it can't be a tough line to tread, but I do feel like some things deserve to be treated with scrutiny, not a systemic level but on a personal level.
There's a great video essay (specifically it's first part) by Dan Olson about Fifty Shades of Gray (the first book and the first movie) that explores this sorta idea really well and more or less is my thoughts on this sorta thing in the extreme.
I'll admit I am kinda biased in this regard. I have a minor preference for stories that are wholesome and straight-forward to some degree and am trying to open myself up to more bleak and uncomfortable pieces of art overall, many of which I do quite enjoy for what they are. I also believe there are plenty of occasions where a story being fiction does mean you have more leeway to explore things you obviously wouldn't want to happen in real life, but I do believe there's a line somewhere that shouldn't be crossed without invoking some sort of justified reaction.
Part of what made me kind of have the "I kinda feel like a fascist for saying this," line, is that I tend to gravitate towards art that I feel speaks to some sort of truth. It could be a very shallow truth. Like it's truth could be, "Sometimes we should just enjoy ourselves and relax," but it is something that feels true and correct. And that truth doesn't have to be comfortable or even affirming. I Saw The TV Glow, before I've even seen it mind you lol, is extremely bleak in it's themes in a way that I deeply relate to and it's kind altered my whole perspective on life if I'm being honest. Themes like, "You have to take action or nothing will improve without you trying," or "No is going to come and save you," are themes that I think feel truthful and worth saying, even if they are uncomfortable to hear sometimes.
It's a common fascist belief that art should serve a purely utilitarian or straight-forward purpose and that "degenerate" art, which usually was just anything the ruling party or group didn't like or made them uncomfortable, should be prohibited/destroyed. I despise this idea for obvious reasons and don't believe there should ever be any sort of genuine state-sanctioned prohibition on difficult art, but I myself am kinda turned off by some pieces of art that strives to be challenging on an emotional/personal level, so therein lies the issue. I sometimes feel the impulse to say, "This piece of art didn't inspire any sort of productive emotion or call to action, I felt like I just sat through something sad and/or miserable," and I ponder what value it brings to the table. Now, this is almost always a completely irrational response, and usually it just takes some time for me to understand what it was trying to say and why it made the choice it did, but I almost never get it initially. And regardless, I don't think my personal discomfort should ever translate to actual praxis or policy lol.
Anyways sorry a bit of a tangent, I guess what I mean to say is that I have a hard time understanding what a story like what I mentioned above says about the human condition or about truth, even shallow and straight-forward truth. I guess I would be tempted to view stories that don't have any of this nuance or just outwardly celebrate doing evil with no conflict or introspection as just bad if not really bad art.
To attempt a TLDR; I definitely believe some stories with these traits existing makes complete sense and accomplishes a specific artistic goal. I just am conflicted over why you would want to write an non-introspective story about a person doing evil and openly being romanticized with no catch at all. Perhaps the point of the above post is more nuanced than I'm claiming, but even with some of that supposed nuance, I feel as if the public having it's own non-systematized reaction to art that they feel crosses a moral line can often be justified. I do believe fiction shouldn't be formulaic or be forced to only fit within a narrow framework, and part of my disgust may be down to personal bias I will readily admit. I obviously don't want this kind of overt censorship to by systematized, but I do personally feel as if even if I don't believe something should be coded in law it might be worth scrutinizing or critiquing.
I dunno, that got kinda rambley, and tbh I'm not married to this position, I could easily have communicated something really badly but this is at least pretty close to what I think I mean. Sorry if anything I said comes off really callous, I appreciate your response!
