I think it was the same person who ranted in a comment about how all human beings are evil because they don't respect his status as an "otherkin" and are species-supremist and are willing to eat him because he's "not human". I think there was much more going on psychologically than their (claimed) NPD, I think.

That said, taking into consideration the effects of the words we use isn't a bad thing regardless, so it's not like entertaining the concept of banning the word was a negative.
