pornography may very well be artistic expression, or what have you, but ICANN was not trying to censor pornograpy, that was just the idea everyone had that was a possibility with the new extension. ICANN was merely proposing an organizational implementation.
I think all sites which contain porn in it should be given a .xxx extension as it will be helpful in keeping the site away from people who don't want it and just by looking at the extension any user will also come to know that what the site is all about.
