The event that was due to start today has been shut down by the Chinese police. As the Guardian article concluded on Tuesday:
"Officials could show up and say 'your fire hydrant is in the wrong place. It is still a sensitive issue."
So today they did indeed turn up and said the event had not followed the "correct procedures", such a 'clear' reason of what is wrong is obviously difficult for organisers to appease the officials. I hope that Google.cn make this a special icon on their front page.
So the country that only decriminalised homosexuality 13 years ago and declassified it as a mental condition 9 years ago has either found a fire hydrant in the wrong place, a wrong date on a piece of paper work, or chairs no aligned in the right way as a reason to halt this step forward.
