Maori academic Margaret Mutu provides an excellent real-life example of Mark Twain's famous quote about how it is better for one to keep their closed and let people think they are a fool, than to open it and remove all doubt.
Mutu's initial comments on race were inexcusable, even if there may have been a kernel of truth somewhere within what she was trying to say. But she made the point clumsily and ended up offending just about everyone.
Her subsequent attempt to justify herself, on the grounds that it wasn't racism because Maori weren't in a position of power (ignoring the fact that she, a respected academic, was in a position of considerable influence and authority) was a genuine laugh-out-loud moment.
And now she's still opening her mouth. Someone stop her, for her own good.
