I can say whatever I want about geeky guys who play RPGs, since I am one. That is basically what most of my friends are as well. I am not stereotyping them and yes they are attracted to women who aren't into games. They just pine for women who are gamers, that is even more attractive to them. It isn't just a stereotype for D&Ders or RPG geeks either. People want to be around others who are into similar things.
I use statistics to make a point and maybe I stereotype here and there, but it is almost always based on some personal experience of mine.
