Well, I'll try to answer these as succinctly as I can:
-For your first point, people do cite, all the time, these "studies" that show men and women playing nearly equally. A skewed fact, of course, that I dismiss, at least for the more action-oriented, violent genres men seem to prefer. For example, you know why Pac-Man was so popular with both sexes? Because Toru Iwatani intentionally made the game non-violent just so women would play. And as for male gamers harassing women, that's unfortunate if true, but it wasn't an issue discussed in the blog.
-Don't see where you're going on the next point. Is five years not enough to show that the industry has changed to accomodate women more? And I can go back further if I must, naming everyone from Terra and Tifa to Jade and Krystal and so on. Truth is, the industry has reached out to female audiences about as much as can be expected considering current gamer demographics.
-Your third point is also disingenuous. Video games are art. Why should developers compromise their vision by forcing a female lead into their game? For example, I like to write, and I tend to write books about male protagonists. Why? Because I understand them best. So if a group of feminists suddenly began berating me because I didn't have enough female leads in my story, I would greatly resent that, and rightfully. Developers have no obligation to cater to a certain crowd if they don't want to.
-"Tropes are evil" is a convenient bullet point mixed with a little facetiousness, but it's true enough. Any time a woman is portayed as "weak"--in other words, when she needs to be rescued or aided by a man--there are always those who wail against it. It's the same with the Princess movies Disney releases: there are always feminists screaming about the antiquated way women in those films are portrayed. Forget, of course, that those films teach compassion, selflessness, and virtue--because the female leads aren't brash, outspoken and/or tough, they're suddenly bad role models instead. And it's the same with games. Poor Princess Peach has been criticized so many times, it's really unbelievable. And silly.
Anyway, as I already said, the industry is not perfect, and more work can be done to bring women into the pastime. But yes, we do need to be realistic. I don't foresee there ever being a time when women are playing God of War or Call of Duty in equal numbers with the guys. And it's not just because we mean old men push them away. It's because, on the whole, women don't embrace violence like men do. And you know what? That's a good thing.
