No, the point of the article is that the mainstream writers/commenters are actually more accepting and more open, and often have something insightful to say, and that the long-standing members of "nerd culture" are being the assholes in increasing numbers.
Basically, Geeks reclaimed the word geek from negativity, and as such the culture grew, spread, and was accepted on a much wider basis than before. And now there are those who don't like the idea of that happening, who are reclaiming the word Geek back into the negative, and in doing so are shifting the term "Geek" into "someone who is into pop-culture who is shortsighted, sexist, homophobic, and angry about the concept of change in general"
"Geek Culture" didn't get co-opted by anyone that wasn't already providing Geeks their culture in the first place. Punks made their own music. Same with Hip-Hop. They made their own art out of what they had. But being a geek is absolutely defined by buying something some larger company has been selling you. It's almost impossible to be a geek without being tied up in the consuming of mass-produced product of one sort or another, be it comics, or TV shows, or movies, or video games, etc. etc.
So railing against "the mainstream" will always ring false to some extent because of that.
There we go.
