You do realize Null runs 9chan, which allows lolicon/shotacon, so long as it remains within legal limits according to US law and is posted in the appropriate areas he has designated. I allow topics like the ones you mentioned to be discussed in the context of how they are used in works of media under the same limitations on my own site, because I believe in the same legal boundaries of free speech being sacrosanct like Null has admitted he's tried to stand up for for the longest time.
Both of us have drawn shit for that, me by having a bunch of disingenuous assholes try to paint me as a degenerate in the same manner Null has been painted as one by his own enemies who want to forget defending free speech means defending speech that is vile, contemptible, and even degenerate, but as long as it's legal to discuss, then it deserves the same protection as speech that does not offend and is pure as the driven snow.
In that regard, he needs no advice whatsoever from me.
