Can we finally retire the word "rockist?"

Now that the High Fidelity school of music criticism is aging into obscurity, and the word "genuine" as applied to popular music rendered all but meaningless, can we retire the term?

I'm trying to make sense of Emily Mackay's Quietus post, "Rock Against Rockism: Why Liking The Boss Is Not Conservative." I think she's making two disparate points: one, that liking guitar-driven hard rock doesn't necessarily make one bigoted (see below); and two, that electronic music is more progressive than mainstream rock and pop. Before I get to the first -- which merits a larger discussion -- she made some pretty salient observations about gender and pop music, specifically how women playing and creating the same music as men are still viewed differently:

"I do wonder what people are on about sometimes when the just as stylised and retro synthpop and industrial electronica of the likes of La Roux (who I love) or Zola Jesus (who I also love) get no such stick. They're women, you see, with keyboards, so that means they're from THE FUTURE. Are the likes of Client, with their haughty, I-am-a-sex-robot, Euro-froideur more modern because they wear PVC dresses and fetishise cold electronics rather than licks? Or are they pretty much Brother with a different, more critically acceptable set of references?"

As for the title's inspiration, Mackay linked to an NME article (which linked to a Daily Mail one in an endless game of hotlink telephone) sensationally titled, "Study suggests listening to Bruce Springsteen [read: guitar-driven, hard rock] could make you racist." According to the article, when white college students listened to mainstream rock, they favored funding toward other white students, rather than black or latino students.  Mackay adds:

"There's no need to look for something inherent in the nature of mainstream rock music that attracts or makes bigots because some idiots like it. The history of rock music, an older form than rap or dance, has historically been dominated by white men. But then, a lot of things have been historically dominated by white men. We're getting there with that, you know, and there's no need to throw the riffs out with the bathwater."

All true. And if music is part our culture with its deeply woven and systemic racism, of course those values seep into the music. It's far more complicated that just saying "listening to x or doing x makes someone racist."  I would have loved a more nuanced discussion of that, or even why some music is considered "art" while other "commerce," but instead she spent the brunt of her post defending her love for guitar rock. It reminds me of the arguments choice-feminists make that every choice is a valid one and no one should be judged for theirs. Also true, but our choices don't exist in a vacuum.
