It’s unanalagous in that HOI4 sanitized itself of the Holocaust specifically so people wouldn’t be able to roleplay committing xenophobic genocide, unlike the game in question which is specifically designed to let you roleplay a pedophile rapist preying on the already abused.

Fair. Follow-up questions:

1. If someone mods HOI4 to include aspects of the Holocaust and all the other Nazi stuff, does that make this particular copy of the game hate material? (IMO: it would be in areas where Nazi symbolism is banned, similar to how Norwegian law makes Dorei to no Seikatsu illegal there. People’s opinions on the material are irrelevant, it’s what the law of the land says)
2. Conversely, if Dorei no Seikatsu hypothetically censors or tones down the graphic/explicit portions, but the story essentially remains the same, would it be considered CSAM in Norway?

However it is tangentially analogous in the sense that anime tends to have a bit of a Nazi bar issue with pedophilia thanks to people (who I’m gonna have to assume are well intentioned) unintentionally making room for pedophiles to exist and operate with arguments just like the ones you’re making here.

I see the concern that pedophiles continue to abuse children. There’s degrees of handling the problem, up to and including measures like Chat Control and Britain’s Online Safety Act. Now, do the people have the appetite to be subject to those measures?

Which leads to…

Preventing government abuse and corruption is separate from stopping the distribution of CSAM and protecting children from predators.

I don’t trust governments eroding privacy and surveilling its people because of predators. They pass those types of measures with other goals in mind.
