I think you're completely wrong, Sade didn't have the profile of a powerless imageboard browsing nerd who fights his sexual frustration by indulging in unattainable depraved sexual fantasies. No, Sade was actually a TRUE degenerate nobleman who used his privileges to actually indulge in all sorts of debauchery as a sexual predator until he was unable to. His writings are actually the continuation of the philosophy he exhibited during his life, attaining pleasure by demeaning other.
