I think the crux of it is despite being a gamer, the author wants to distance himself while criticizing said "gamers" from his high horse. Also, the author admits to avoiding multiplayer so it's mostly his opinion on secondhand information from female gamers (selected from a pool of the most offensive stuff).
Not saying that etiquette isn't an issue but this article doesn't really advance the cause. However, the way you call out the behavior and setting an example is really the only viable solution.
One perspective is that this "real gaming" is like a sport with the physical component completely removed and the players completely segregated. There's zero stress to your cardiovascular system and zero possibility of physical injury due to contact. In other words you're free to run your mouth while enjoying the hormonal surges of high competition in an anonymous setting. I don't think that makes a trash talker a maladjusted social misfit though.
I agree that the "gamers" as defined by the author are a rowdy bunch (for lack of a better term) but I have a hard time understanding the author's motive. Is the article trying to bring a feminist perspective to gaming?
While it would be nice if we could all be respectful of race and gender while shooting at the pixel versions of each other, what problem does it solve? Do we want more female gamers? Is this behavior of immature people anonymously venting or raging harmful to society or to the individual's development?
Games are really one of the few outlets for aggressive behavior in the modern world with zero risk of physical harm. It satisfies competitive urges and requires a variety of mental and physical coordination skills (that may or may not be domain specific). Even if you cleaned up the language used there's always going to be trash talk and new "leet speak" or euphemisms to get around censorship.
It just reads like a half-baked article that lobs a blanket insult at male gamers without any real substance.
As an opinion piece I think it does more of a disservice than anything not just with the blanket statements but the author basically does the very thing he's criticizing only in more civilized language, essentially calling "gamers" (of which he conveniently disassociates himself from) a bunch of socially-stunted basement dwellers.
