There are a number of male feminists these days, from what I'm seeing. I myself am one. It may have to do with the breaking down of the notion that the other gender is the enemy until marriage, and so one should only hang out with your own gender (A notion which always makes me think, "Um... But I'm straight, I -like- women.")
Online gaming doesn't hurt, for several reasons, including:
1) Finding a real, proven female on the net makes romantic RP a great deal more relaxing (I've had 'female' characters try to seduce my characters, or my characters teasing but refusing them, and, when failing, suddenly announcing their RL age and male gender...).
2) Female gamers on the net are, on average, more in to the RP itself than male gamers, which makes them a joy for those males who DO game for something other than to stroke their ego, bash stuff, and talk dirty.
3) Smart women (which are easier to find in D&D than at a football game, though of course, one can like either and be of any intelligence) are fricking sexy, and a gamer, now that the "Lets give females crud stats" era is over, has a slightly better chance, on average, of encountering one to learn the fact. So much easier to appreciate someone who's not trying to be a Stepford-style person because of social training. Yay progress.
