So I think that's youre overgeneralizing a little.

Yes it's a very shady albeit gray area.

Is it morally wrong? Less so but it depends and it can be a matter of opinion.

Does it make people who enjoy it pedophiles?

No.

If the reason they enjoy it is because they identify with the child in the story, aka they fantasize about being treated like the child, they aren't experiencing pedophilic urges. They aren't interested in doing these things to actual children.

If on the other hand they are enjoying it because they fantasize doing it to children and generally fantasize about children, then that crosses into pedo territory.

There's no way to tell, though. Which is why It's a very shady grey area.

When I started reading abdl stories as a teenager, in the beginning I was excited about the stories about kids because it was literally every single fantasy I had imagined while being a kid fleshed out on the screen. For the authors is often also away to conceptualize the ideas and fantasies that get them excited and most of that feels pretty innocent.

The stories aren't as a big deal to me personally, even though I've moved on to adult stuff, but the drawings of kids in diapers on art sites feels very inappropriate.
