I had a similar reaction--I was surprised that few people seemed to cringe at Jared Swilley of the Black Lips' repeated reference to Wavves as a f-ggot (BV's YouTube linking of the f-word notwithstanding). But then again, I wasn't really that surprised. Perhaps the policing of language and profanity--even as it borders on hate (or unless it is uttered as hate?)--now seems like the pastime of a passing generation.
It reminds me of the much-discussed reluctance of the Times to call the excellent Toronto band Fucked Up by their name. How can we even hope to guard against offensive speech nowadays? I find the whole idea of profanity in a digital age, or at a moment when speech becomes "public" in all these new and once-unimaginable ways, to be somewhat quaint and outdated.
