He was wearing these tango high-heels just like all the other followers on the dance floor at the recent USA Tango Championship — except that Claudio Marcelo Vidal is a male dancer in high-heels. And that, apparently, was more remarkable than anything else, even for people in ‘oh-so-open-minded’ San Francisco.
