I'm criticizing the way they are perceived. I was going through a book of Marina Abramovic and Ulay's 1970s performance work the other day. These people did two, even three Documentas or Venice Biennales over the course of a decade without any fuss. They would just treat it as any of their other engagements, with the same level of dignity and commitment they'd reserve for a one-day event in a small gallery on the Austrian mountains.
