See my comment two posts up.
This is not controversial nor should it be.
There is one person who is a well known apologist for the Chinese communist regime who brought it to that level. A fellow traveler showed up to support him.
And, the things these two used were nonsensical as attacks. For example, one stated the exact same thing I did and then used that to attack me. It made no sense.
In the context of Chinese communist political struggle, though, that is not unusual.
Thanks for the plot summary. Obviously I have no idea about the back story, which is why the conflagration on such a topic sort of took me by surprise. Also, I don't speak a lick of Chinese, so I'm not in a position to judge the merits of the competing claims here. Otherwise, it was a bit like wandering into Chuck E. Cheese, and finding a full-on barroom brawl in progress - not quite what you expect to find in there :)
