This one is particularly interesting because Clement is the grandson of Sigmund, the Jewish pseudo-scientist who popularised the idea of children having sex with adults. His theories were based on the idea that children wanted to have sex with their parent of the opposite sex (the so-called Oedipus and Electra complexes) and, consequently saw their parent of the same sex as a rival for their affections, giving rise to jealousy and hatred.
I've commented before on how ancient Jewish and Islamic texts pathologise and bestialise the outgroup, whether goyim or kuffar, depicting them as impure, contaminated, disease-ridden. Freud's pseudo-science strikes me as a modern incarnation of these ancient tropes, pathologising the goyim. It has been shown that Freud deliberately lied about some of his case studies, including presenting as fantasies what he knew to be real (see Against Therapy by Jeffrey Masson).
His grandson's paedophilia does raise some interesting speculative questions. For example, is it possible Freud himself was a paedophile or had paedophilic tendencies and developed his theories, whether consciously or subconsciously, to justify paedophilia and put the "blame" for it on the child instead of the adult?
