Similar thing, though due to different reasons, with Mein Kampf - I seriously doubt more than a minor fraction of all neonazis read the whole thing because:
1. It's a brick at ~780 pages in the full text version.
2. The Austrian painter was an even worse writer and the book reads like a huge rant the likes of which you could read on Voat back when it still existed.
I recommend people read it so you can understand how people like that think. This is also a valid reason for reading Lolita (although at least Lolita is well written).
Just skimming the Wikipedia article, it seems like conspiratorial thinking is a factor. That reminds me, I need to sit down and finish the new Contrapoints video on conspiracies
It has been years since I read Lolita, but I don't think that one comes away from it with any insights into the mind of the pedophile. It was pretty clear in reading it that it was a grim story underneath, something intermittently mentioned by the narrator.
