This half? What half? As I said, people not interested in this hobby mostly say they'd rather do something else than sit around a table and roleplay.
That's factual.
Have you missed the people telling you about female gamers who have left the hobby because of dealing with misogynist behavior from fellow male gamers?
I have read on EnWorld guys who defend not allowing woman at their table because woman bring nothing but drama. I can totally get the idea that some guys view game time as a chance to be with the boys and that is fine. But when I read statements like female gamers disrupt the game because all the guys go goofy over them so I don't want then at my table. That tends to get my back up. Woman get excluded because guys act like goofy little boys is rather unfair.
The guide to female gamers is supposed to be funny and poke fun at the stereotypical female gamer. I remember when it came out and the guys I game with had a lot of fun teasing us woman about it. So we got together and did a little stereotypical male gamer book. But it made me wonder why this book was even necessary and where was the companion to it on dealing with male gamers like cat piss man or mouth breather man?
Woman gamers get stuck with all the same stereotyping as male gamers get plus the whole female stereotype as well. We can't really change how the outside world views gamers but it would be nice if in our hobby we didn't have to deal with some of this crap we deal with.
