Like, for example...he talks about World of Tanks being fantastic and hardcore and then says, "you won't get many wives playing it." As though being a wife and enjoying fantastic hardcore games are mutually exclusive. Or even the less offensive, but still frustrating, comment about folks who only play sports games with their friends being "not-gamer gamers." So on and so forth...I'm not going to pick out all the quotes, don't worry. But, like...he assumes a shared definition of 'gamer' without having ever explicitly stated that definition.
Both of these seem to fit well to me.
So...you're assuming all the women gamers out there are unmarried? Or are you just assuming there aren't that many women gamers? Why do you think that enjoying hardcore games and being a wife are mutually exclusive?
I think @burgertrench covered it pretty well. I feel you're trying to dissect what was said a bit too much and now trying to put words in my mouth with your assumptions about how I think. Demographically, there are fewer women playing games like World of Tanks then men. When you think of people who solely play sports games, they don't fall into the gamer profile. Simple as that.
