>I don't know, linking human psychology to the internet and bringing out the worst in people is a bit far fetched.
Libraries give information, but within the context of a dry, academic, lethargic environment. On the internet, some impressionable fools are able to find like-minded idiots, and achieve confirmation bias. A little knowledge is a dangerous thing.
Beyond that, it is hard for me to judge in personal experience. I'm just glad that I came of age after 'gonzo' pornography became the norm (through the internet*). It's weird being with women ten years younger than myself and have them ask me what I want in such a way to infer that their perspective and that of their past partners has been informed by stuff they've been watching since their early teens**.
As an adult, I have no problem with the Marquis de Sade... it's clear from his comments about wanting to rape the sun that he was expressing a vector, not a destination, and that itself was a valid comment upon the insatiability of desire. Or whatever. The point is, I'm not taking him literally in a 'monkey see monkey do' kind of way. My views are informed by drinking lots of tea and beer with individual females.
*Of course, teenagers in mainland Europe in the 1990s could get their fill of smut from cable TV. Knowing them as adults in their twenties they seem just as well adjusted, if not better, than us censored Brits. Somerset Maugham commented about the inverse relationship between sexual material and sexual violance.
** Nothing new. According to one old dear, sat in her garden with a pith helmet and a garden gun because "the herons are after my gold fish again", anal sex was "all the rage" in the 1930s. One can't get pregnant in that way!
