Hypocrisy is really not as useful as people think. Imagine if some man, who beat his wife, made a career of talking about the important and harrowing issues of domestic abuse.

People would rightly scratch their heads at such an over-the-top hypocrite. But surely, the man would be correct: domestic abuse is an important issue. And imagine a response from the peanut gallery? "I'm not going to stop beating my _own_ wife until that hypocrite gets his comeuppance!"
