Yeah, the stats help. There's been a lot of comments in various places saying "there isn't really a problem! Look at Vanyel! And the Mortal Instruments series! And Dumbledore is gay!" Which is kind of like saying, "there are plenty of black authors in SF/F! There's Samuel Delany, and Octavia Butler, and Nalo Hopkinson!" Yes, those examples are real, and yes, there are more that could be named. But the existence of such examples doesn't negate the general pattern, which is that representation in the genre is way below representation in the populace.
