Like, that entire "romance" section in the library has tons of, ummm, steamy scenes in it. Difference? One is a manga and most people assume kids can read it. Just like when I went to see The Watchmen in theaters and saw parents bringing their kids in. Responsibility. At this point, it is completely the parents fault: to show how stupid some are, my wife use to work at a video rental store, and PARENTS complained when they let their kid watched Knocked Up.
For fucks sake, what do these people expect?
