Some of the examples in this thread itself shows how moderation isn't easy. There was a link to a thread about an an Australian Diplomat calling for emergency visas for white farmers. It linked to an article in the NY Times.
Some said it was racist or race baiting. I can understand where they are coming from. Others were fine with it.
I reported this thread a day or two ago (maybe not for the first time) and it's finally deleted now. The problem in this case wasn't the article but the title of the thread -- the thread title ended with "...for White South African farmers - They know there will be a genocide"
But the article itself didn't say anything about genocide. And the article is mostly about the ridiculousness of the politician who made the comment. So the post was pretty clearly race-baiting.
