I really don't think "Male gamers" have to do anything.
The vast majority are reasonable people. You have to realise a lot of the running and shouting of "Male Gamers are sexist" is done by, frankly, very stupid people.
These people, simply lack the capacity for a decent argument, they lack the ability to consider a wider field, instead they simply see a small group of people, and decide that "This represents all males!" and begin their frankly deluded crusader to "Bring down the patriarchy".
Despite that fact that people around the world, regardless of race and gender, elevate themselves to whatever position they desire, they seem to believe the reason they're incapable of such is due to their gender, sexual orientation, or even race.
The majority of female gamers I know, really pretty much on equal footing with male gamers.
I play a lot of MMOs, and thus "This armour is terrible" comes up a lot, but, beyond that, most seem perfectly happy.
So, frankly, whatever it is this people are spouting, none of it seems evident in my experience.
