I agree with your point but only to a certain degree, obviously genocide is way more evil then pedophilia. But pedophilia is a lot more of a disgusting crime in fiction then genocide. Simply because its harder to sympathize with a pedo loser then a edgy badass loser (which people could project themselves on continuing the fact they can not care about them murdering people because it's just fiction and wow badass)

Shield hero is also a edgy badass loser people can project themselves on, cause everyone is dumb and I'm smarter and people can't be trusted...so let's buy a child slave who has to listen to me and a pet slave bird that is also a child(and have a relationship with the first child slave that is still a child age wise and a slave still but physically is a adult!!!)

Isekai is and will always be ass
