OK, so sincerely, without joking, you are really fucking dense lmao my dude.
The entertainment is not CP... it includes Joelle naked (she's the most beautiful person in the world, remember), looking at the viewer and saying she is so, so sorry. The lens of the film is altered to approximate what the world looks like to a newborn baby. This is mixed with DFW's psychocosmology he makes that's obsessed with the Magna Mater (great mother) Jungian archetype, the mother who devours you whole (psychologically speaking), who kills you in one life and gives birth to you in the next, like Avril's black-hole personality, like the Oedipus complex/Hamlet and Gertrude, Hal having a Coatlicue complex (Coatlicue = Native American devouring mother goddess who represents the fertility of earth and also its destructiveness, portrayed as having many snakes wrapped around her, gave birth to many of the gods).
"ephebe" ... OK, this is just because you're a wussy and a bit afraid of any language that's strange, overly physical, etc. A lot of artists are "creepy" in this sense, overly real and about somewhat oversexual details. For instance, I remember an exchange on here I particularly liked where someone criticized Joyce writing about "the scrotumtightening sea" because it made them feel awkward, then some other person BTFO'd them, basically calling them a pussy and afraid of anything concerning the body or sexuality.
Moreover, you're misinterpreting it too, because ephebe also historically means:
>(in ancient Greece) a youth about to enter full citizenship, esp one undergoing military training
Which clearly relates to the kids training at ETA.
Third, "I have become an infantophile"; Hal knows Latin; he memorizes which words are Latinate and which Germanic in etymology; he notes that the sign "EXIT" would read "He leaves" to a native speaker in Latin. This is all in that first chapter there, for a reason.
Infant in Latin means "mute", "unable to speak", "speechless". Hal has become, not a lover of infants, but a lover of being mute. Also a lot of the book deals, from a range of subtlety to really obvious ("getting in touch with your inner infant" at the end), with the theme of infantilization, associated also with themes in the book of catatonia, stasis, paralysis, inability to communicate, and even (yes I must get Freudian here) castration
But while the infant for much of culture is something despicable, worthless, annoying, puling, weak, DFW on the other seems to glorify it. Hal, in becoming infantile (watching Infinite Jest the movie reverted him to it?) has been redeemed. Like Mario, also something of a grotesque helpless infant. DFW associates infanthood with greater sincerity, greater love, a greater naivete, a paradoxical strength in weakness in true Christian fashion. "Verily, you must become children again to enter the kingdom of Heaven."
However, you're right, maybe he was just a pedophile after all
