Yaoi manga
If u don't like reading manga with rape, murder, shota, abusive or any other dark or malicious content in it then just freakin avoid it! How difficult it is for you to avoid it and treat it like it doesn't exist to your world. There's no need to go and insult or degrade the author or the story itself. I don't freakin care if you voice out your opinion but learn not to cross the line. (Sorry for ranting)
