Just because it has always been done, done mean it’s right. The Venus of Willendorf was created by a person from an early human society. It is just as likely a societal problem as a biological one. How do you know the creator didn’t get slapped by a woman when he showed it to her? Either way, we are not cave men. We can reflect on societal values and change them when they don’t suit us. There are actually lots of women in tabletop games, certainly less so in 40k though. There is an episode of South Park about it. But if you clean yourself up and present yourself nice, I’m sure some woman will eventually bite. Hopefully figuratively, not physically.
