Did you even read the linked thread? It was a pitting of Dio for accusing each and every single polyamorous woman of being an emotionally damaged wreck who could only possibly feel as they did if they suffered (probably sexual) abuse. In fact, when a woman offered her experience as a refutation, he actually accused her of only holding her position because “you must have gone through some serious childhood trauma (abandonment, maybe? alcoholic parent? Something worse?)”
Dio has a tendency to do that sort of stuff, actually, although I don’t have threads at my fingertips. He gets an idea in his head about a group of people, spouts off ignorant and offensive crap, a tranwreck of a Pit thread develops, and eventually he backtracks a bit under withering fire. Hell, my first Pitting ever was because he actually had the nerve to claim that the US military was “engaged in a campaign of genocide” against Iraq.
I’m surprised you don’t know this after posting on the bord for as long as you have. Dio has a reputation for being one of the most stubborn people on the board. Hell, just search the Pit for his numerous pittings.
