Amanda Palmer has suggested that there's well over a dozen women who have come to her with complaints, so this scandal is likely just getting started. And Gaiman's podcast about it didn't help, and if anything seemed to confirm at least inappropriate sexual harassment of young girls that worked for him. If not worse.
But nobody's talking about that because Gary Gygax said something that offended literally nobody at the time, but over forty years later is controversial. Even if you're NOW offended by Gygax, that still seems like a strange prioritization of things to be concerned about.
