Quite frankly, all the arguments about how these genre/materials encourage immorality (pedophile, killing, rape etc.) in real life are so stupid. No, I'm not going go on a killing sphere simply because I've been playing CoD, I'm not going to suddenly be into incest and all that gangbang or mass killings because I read GoT, I'm not going to turn gay because I watch Sailor moon with Sailor Uranus and Neptune a couple, or that I'm going to be a cannibal because I watch/read Hannibal series and I like the MC, and yep, reading loli/shota manga doujinshi or heck, reading Ban making love with Elaine in Nanatsu no taizai etc isn't going to make me like real living children any more than I am currently, which I don't, least a pedophile. If you have problems differentiating between real life and fantasy/2D materials, go consult with professionals and seek help. If you see your friends showing behaviors like that, reach out to them as well and try to help them. Senators and lobbyists or whoever should make it less of a stigma and easier for people to see psychiatrists and raise awareness of mental disorders rather than putting the blame on media (not just manga, anime) like this.
