What articles I was able to find by Watkins and Bentovim seemed to be dealing primarily with the sex abuse scandals in the Catholic Church, and they seemed to be shot through with an attempt to convey the idea that what some rogue Catholic priests were up to with the altar-boys is common behavior in the secular community as well. A suspicious looking attempt to justify the behavior by claiming that "everybody does it." This sort of motivation tends to skew any attempt to provide "scientific evidence" for a particular viewpoint.
