You friend is, essentially, correct. Although there is a legitimate “chicken-and-egg” issue here, i.e. “did the media create the demand for salacious fantasies or do they merely service the public’s pre-existing appetite?”, there is no doubt in my mind that there is, indeed, a formidable appetite for drama for all things kids and sex. It’s titillating and exciting to the public and for all of the reasons one can imagine. It’s entertainment, pure and simple.
