Always consider statistical effects - in this case, our personal gaming experiences, and the reporting you'd see on EN World, are probably going to have been subject to a heavy selection bias.
Like, I was a nerd, but a "good kid" when I started playing in the 80s. Other boys who talked like that about women made me distinctly uncomfortable, and I avoided them. I certainly wouldn't sit around playing games with them for hours on end. I effectively curated my gaming experience in that way, to exclude sexual violence in play.
But that actually implies that folks with other attitudes would be doing the exact same thing - effectively curating themselves into groups that did play in that way. And those two bubbles would not cross too often.
And then, on top of that, EN World has rules of behavior that are not terribly welcoming of folks who suggest such stuff in play. We should expect an over-representation for less-misogynistic play on this site. We might naively take that to mean that sexual violence in play were aberrations, or had ceased due to cultural shifts, when it is perhaps more likely that this site filters against their being represented here.
