I wonder if Tibet isn't achieving a certain subversive chic in China, even as it is the subject of intense fury from young, nationalist bloggers.
My evidence is anecdotal: Cui Jian's use of Tibetan music during his allegedly anti-Olympics concert (though why, exactly, the concert was "anti-Olympics" beyond that some German reporter said so, I don't know) and Zheng Jun's new comic book about a heavy metal "Tibetan Rock Dog" playing the underground Beijing music scene.
So... this "trend" might not be a trend.
But, if it is a trend, it might be meaningful. Think of the U.S. counterculture's embrace of the Zapatistas in Mexico or, decades ago, the FMLN in El Salvador and Sandinistas in Nicaragua (or those Che Guevara T-shirts that adorn many backs, including that of this writer).
Chinese interest in Tibetan culture can often be filed in the "noble savage" category of admiration, just like sympathy for Native Americans in the U.S. But if resistance, too, gets respect, even a little bit, then things are different.
That was true in the United States, as well, when supporters for Native Americans lashed out against settler atrocities over a century ago--to the point that some citizens grumbled that Indian atrocities weren't getting enough attention--or, more recently, backed up the American Indian Movement's quest for greater autonomy.
