This thread is built on the cornerstone of nausea. Its walls have been put up with slabs of repetition, and its roof is paved with shingles of some other noun I can't think of at the moment to complete the metaphor with.
There are some truly warped people in the world. Saying that viewing drawn fiction about child porn will not ever affect anyone is stupid. Are there people who have sexual attractions to children and read lolicon doujinshi? Absolutely. Is everyone who reads lolicon like that? I'm under the impression that loli does not necessarily equal child porn, so no. In the case of the title originally being discussed, it looks more like "cute little girl has a crush and hilarious hijinks ensue as she vainly tries to win him over" than "sexy little girl gets felt up by her school teacher."
The same principle I use with violent video games may also be able to be applied here: With some people, yes, this can affect them. It is the job of the parent to make sure that the child knows that such behavior is wrong, and to keep suggestive materials away from them. Of course, pedophilia is a little different, but the same idea holds.
As to whether or not this sort of stuff will ever truly be accepted in the US… I highly doubt it.
What the…? Why have I not seen you here? You're new?
And with one post, you've equaled the neccesity of all the posts I've ever made?!
