It seems Matt Nisbet thinks that PZ Myers needs to shut up and let more competent people talk about science. More competent than what? More competent than an atheist? Is he possibly suggesting that only theists should talk about science? Or worse that there is some kind of don't-ask-don't-tell policy for speaking about science?
Either option is flatly unacceptable. And I'm afraid I don't have a well thoughtout properly framed answer for Matt. My only possible response is it's time for Matt Nisbet to shut up!
