The Pink Palace, Notre Flame` and the German Orgy instant are clearly post-V2. No explanation for that yet.
All are certainly post-Vatican II but we need to avoid the fallacy of "post hoc, propter hoc." Each is also a phenomenon which appeared after the discovery of the Galapagos Islands. Nonetheless, neither those islands, nor their turtles nor he discoverers of both had anything to do with Notre Flame, et al.
The remote explanation of all three of the admittedly execrable three examples which you cite is, of course, the misbehavior of Adam and Eve as to the fruit of the Tree of Knowledge and as to their obligation to OBEY. Without the Fall, there would have had to have been another source of concupiscence. More recently, the cause would be the refusal of Benedict XIV to continue the anti-Modernist efforts prescribed by Pope St. Pius X and the failure or refusal of each of Della Chiesa's papal successors to re-assert the campaign to exterminate the Modernist heresy as instututed by Pius X. Of course, Marcel the excommunicated patron "saint" of defiance, was excommunicated by John Paul II and not by Benedict XIV, Pius XI, Pius XII, John XXIII, Paul VI or John Paul I and so the schismatics regard JP II as the ultimate papal "criminal" in the history of the RCC. Lutherans are not fans of the pope who excommunicated Martin either and therefore exaggerate the importance of that pope. Nothing new here. Luther also claimed to be "reforming" the RCC but we all know better than to believe that. Likewise the SSPX are as rebellious and essentially dishonest in their claims to Catholicism as was Luther after he fell for the presumed charms of Sister Katy.
