When I say "empirical," I mean actual studies, like when a scientist has a hypothesis, performs a reproducible experiment, and draws conclusions based on the results of that experiment. Not a blog article where a woman complains about "douchey white dudes with entitlement issues" who were irritated that she started disrupting the forum. (Ironic that a feminist who thinks that a show should cater to her whims is calling others entitled, but that is beside the point.)
Chances are, the assessment that she was using her "crazy, over-emotional lady problems to ruin everyone's good-natured fun" were true. If you come screeching into a forum where people are discussing the plot of a television show and start accusing the show of racism and sexism and classism, you are ruining things. This is especially true when her attitude is ugh, douchey white dudes.
What you're asking for likely doesn't exist because no agency is going to give out grant money to do a scientific research study on sexism in D&D. There are general studies on sexism in fantasy, games, and videos, though you're probably going to have to pay to access some sort of library or journal for that information. You aren't going to get those kinds of things for free.
