Apparently, subcultural chaos has struck Mexico. Attacks against emo kids from anti-emo youngsters have resulted in organised counterstrikes from the emo community. Daniel Hernandez provides a summary of the culture clash on his blog (in English).
My Spanish is a bit shaky, but the video below (from an emo rally in Mexico City on March 15) is clear enough (although I'm not quite sure about what the Hare Krishnas at the end of the clip are trying to accomplish).
It's a viral, however!
