It sounds like you've also made up your mind before reading it. How about taking a look and making some counter arguments to their findings so that people who disagree can argue on that basis rather than the basis of your speculation?
Are we clutching pearls? 90% of the popular porn videos show taboo fantasies centered around--at the very least--spanking women. Is that not interesting? We don't need to clutch our pearls to make note of that and to discuss what it means. Pornography is very taboo as you've alluded to, but HN is for me a place where we can discuss anything that we find intellectually stimulating.
I find it very interesting for sure that depictions human sexuality is apparently almost always in some small way also depicting violence against women. I find it disappointing that so many here want to write off the simple mention of that fact as "moral panic" and discuss it no further.
