Hmm. These 'psychologists' are just like those who published the phony papers claiming that watching graphic pornography is like watching a sunset. (Read up on nofap, YBOP and see their response to these frauds.) It's only natural that they would be the same ones trying to push the "I was born a pederast, I can't help myself" narrative. No personal accountability in their world exists. You could say that this sort of thing started with Sigmund Freud. Look up the story of John William Money and David Reimer. Allen Ginsberg, a poet and member of NAMBLA (panegyrized by Salon Writer Camile Paglia). Alfred Kinsey, a total nutjob in his later years with his sex-in-a-boxes, with a surprising amount of influence on our current culture. To quote a website:

The link between homosexuality and pedophilia is rejected by many mainstream research groups, which have even begun to view pedophilia in value-neutral terms. The American Psychiatric Association removed pedophilia from its list of sexual perversions in 1994, while in 1999 the American Psychological Association published a report, "A Meta-Analytic Examination of Assumed Properties of Child Sexual Abuse Using College Samples," which "claimed child sexual abuse could be harmless and beneficial," according to a 1999 WorldNetDaily column by noted researcher Dr. Judith Reisman.

Edit: A quick search reveals a news article, 'Pedophile Ping-Pong Permeates Sex Horror' from 10/20/2010. http://www.wnd.com/2010/10/217565/ (somebody should archive this in case it gets deleted) Alfred Kinsey's "Experiments" should be investigated. I am almost certain that they are connected to Pizzagate.
