This is interesting, I don't remember seeing more than trace amounts of “nazi/fascist material” there at all. Sure, someone has probably thought that the world needs another copy of Mein Kampf, or has had a real important story of how Jews did 9/11, and maybe these freesites are still (partially) available after a decade or so (I am not at all bothered to check, to be honest), but general amount of such loonies has definitely been at the usual level of any decently sized internet community. As for Freenet forum systems, I can only remember a prolific Frost spammer who was either a persistent troll, or a mentally ill person, neither of which is unfamiliar to experienced internet users. It seems to me that some mental inertia has made you continue the list of “offensive content” with “nazi/fascist material, etc.” after you've mentioned “child porn”.
What I don't understand is the word “exposed”. Let's take Mein Kampf, for example. I am sure have hit upon it on the internet multiple times over the years. I am sure anyone can find its text in no time, even if their native country banned it. Still it never occurred to me to start reading it. It would really be a joke, and I have nearly endless list of better things to read. I guess I was “exposed” to Mein Kampf, so what?
