If I were to write you a story, incredibly implausible but also horrifically and sexually violent and perhaps personally compromising, the JV staff would of course not allow you to read it. Furthermore if they didn't remove it, how many of you would actually read and willfully follow the narrative of the story- even if it placed you commiting attrocious tabboo, such as being a paedophile?
I doubt very many of us would willfully read and process such stories, eventhough the thoughts it would instill in us would be vapid and ultimately harmless; it would make us uncomfortable to place ourselves even hypothetically in those situations.
...and this is the theme of discussion, how far do you allow your mind to wander into the horrific or attrocious realms it may spontaneously explore? Do you blot out such thoughts as a mental discipline, rationally dissect them or just try to think about something else? Perhaps you even fear that other people might, somehow, know and be horrified at your thoughts- and so use that as a justification to stop having dirty thoughts in public.
