I could definitely see the anime to pedo pipeline happening.
The vast majority of anime has underaged protags, usually aged 13-17.
That's already pretty bad, especially given that anything aside from penetration is legal in Japan from age 13.
Then however, you have mainstream anime series with sizable budgets that revolve around pedophilia.
I'll give you one example:
There's this recent anime called Uchi no Maid ga Uzasugiru!
It's about an ex-military buff girl becoming a maid/babysitter:
Pretty standard stuff as far as anime goes but I like buff girls so I was mildly interested.
Then however, the plot starts going and we meet the child she's meant to be babysitting:
OK, you think to yourself: "So what?"
Well, the introduction of the girl has her running through the house with the camera glued to her ass.
They're not even hiding it, the wind blows, the skirt flows and we see her 10 year old ass.
It's also a very expensive dynamic scene with a fluent camera that sadly looks really impressive on a technical level.
...
So it's bad, right?
But then, we get introduced to the main plotline of the show:
THE MAID REALLY WANTS TO FUCK THE 10 YEAR OLD GIRL.
What's that? You read that wrong, you think?
No, the main plot in this shit is a 28 yer old soldier wanting to fuck a 10 year old child.
Just look at the promotional material for this crap:
Like.... what the actual fuck?
And this is a mainstream anime with a budget.
With this shit being distributed worldwide, I think anime creating pedos is an issue one needs to seriously consider.
