Gotta love how the comment section is always full of respectable law abiding citizens.
If its a serious series about killing or mass murders, well, its just fiction, right? Nothing wrong here, keep going. We might even cheer on the killer if he is a cool MC. But if its a comedy about a dude picking up a loli, then lets ignore this being fiction and go to the comment section to make it clear how immoral i think all this is. If this was set in another world where she wasnt "an elemetary schooler", then it would be fine?
I mean, i've read series about kids that age killing other people and i dont remember reading comments about how dare the author write something like that. Or series where children the age of this girl are working, and i also dont remember any comment about child labour... Sexualization of children? Sure, like any other series where minors are depicted with boobs twice as big as they should be. So?
I dont really get where exactly you people draw the line of what is ok in fiction or what isnt, but it sure as fuck doenst sound logic to me.
