In the context of the news story he supplied, I think the point is not to go, "OMG WIKIPEDIA IS NOT LIKE THAT," but instead to consider the inherently "offensive" nature of certain words and whether the mindset of "some words are so offensive that nobody should be allowed to say them" has permeated our culture. Also, where does one draw the line? "Nigger" has been rendered inoffensive in limited contexts, but what of other racial epithets? Where and why does one draw the line?
The news story is about arbitrarily banning a word, rather than banning using the word offensively. Wikipedia has no comparable rules, and I see no evidence that we are going to get such rules.
