Arbitrary is a strange word to use in this context.
Not at all. Arbitrary is as it's defined:
based on random choice or personal whim, rather than any reason or system.
I only really noticed this after writing this up, but I just want to note it seems you're taking my wording to mean the former rather than the latter. I am speaking of the latter.
At the end of the day, that's what art is. It's based on your whims and desires. You can try to order it, but at the end of the day, it's still based on your whims.
in real life, the age of the people around you and how they look; is arbitrary. You have no control over deciding how old a person is or how old you are, nor can you choose what anyone looks like. Those factors are ultimately up to chance.
Who you find yourself surrounded by? Yes, you usually don't have much control about that, barring some exceptions.
But age itself isn't arbitrary. It's dictated by a natural growth process and marked by various milestones.
In a story though, where you are the creator, age and how a person looks is no longer by chance but by choice. Deciding how old someone is affects how that person will behave, how other characters will treat them, and how the setting itself will treat them. Deciding how a person looks is the same as it will also determine how people will treat them too. These are things a creator thinks about when deciding how a character looks and how old they are.
There are indeed things a creator thinks about and they indeed do have some level of planning and thought, but again, they're ultimately dictated by what they want to do. Or I suppose the suits want, but that's going beyond pure art.
To say that "it's not always correct." implies most of the time, it is.
When I read that, I assumed your answer would be, "Yes, most of the time, it is a sign of pedophilia.". Instead, your actual answer is a flat-out "No, it is not a sign of pedophilia." Could you clarify this for me?
That first sentence isn't true. It implies it's correct a non-zero portion of the time. To clarify on that part you quoted: what a casual observer might see isn't necessarily the actual reason for watching something.
If you see 10 roguelite games in my steam library, the obvious assumption here is that I like roguelites. But that's not necessarily the case. Maybe I happen to really like those particular games. Maybe I just bought them because they were the streamer game of the month. Or maybe there's something else, like them being card games, which could be the common theme among them.
But anyways, on my answer:
I'm surprised that was your conclusion. Each of my paragraphs addresses arguments people typically make about underage characters. They are assumptions people make about why people have an interest in it. I address these assumptions and refute them. I probably could've elaborated more on my points but to sum it up:
>This character is canonically X years old
Response: Age has absolutely no meaning in fiction. It is not tied to development or maturity like in real life.
>This character looks like a child
Response: The character doesn't look like an actual, tangible human. It looks like a cartoon.
>But if you have a fetish for this, you must like it irl
Response: Not everything you look at in porn translates to a real-life interest.
I think the unifying theme here is people looking at an underage character and treating it like a real person. But the context surrounding fictional characters is often radically different from reality.
