Oh.. I'm not angry or anything, I just feel that I may have no ability to explain to make you understand me. I'll try anyway..
It's just like a movie about car-thief.. We must not show realistic step 1-2-3 how to steal car otherwise it'll become manual for thief instead and sure be sued by car industry.
We need to keep in mind that some people can't distinguish fiction & reality, some people wanna imitate what they read/watch.. That's why we limit audience type for some kinds. And in case they can't limit audience type, they decrease risk by exaggerate it or make it as fantasy theme to emphasize that it's just fiction.
I have my own rule, I never recommend the sick-violent sex, especially the ones can kill partner like raping by putting traffic-cone, broom, bottle, etc. no matter in front page or in my lists.
Hey, I just wanted to say something about your comment on the manga Nii-chan by Harada (since there's no way to reply).
"≫≫ IMO When it comes to Shota theme, the mangaka needs to be very careful.
If it's too realistic then it may clue a pedophile how to harm kid. - That's DANGEROUS!!"
By that logic, then we should ban all realistic kinds of fiction containing criminal acts (such as rape and murder), not just pedophilia. That would be very boring.
