Michael Rosch at Examiner suggest that Mooney and Kirshenbaum suffer from a problem he calls ‘the paradox of paradise’:

They call for a non-confrontational approach to things and desire an ideal world where everyone just gets along, but they themselves create conflict with their own critics because they realize their ideal world can’t co-exist with dissenting views. So those most advocating non-confrontationalism pick fights with those who disagree with their philosophy and see merit in certain conflicts. Hence the fact that in addition to criticizing Dawkins, M&K go after their other favorite targets, PZ Myers and Jerry Coyne, each of whom wrote scathing reviews of M&K’s book. So they gave your book bad reviews because they found your conclusions superficial and naive? Get over it already.

Actually in their case I think it’s not so much a paradox as just not noticing their own inconsistency. As several people have been pointing out, they’re saying something along the lines of ‘God damn it be nice and get along you miserable piece of crap!’ They’re talking about peace and harmony but they’re performing combativeness and truculence. But anyway, it’s the part about the ideal world being unable to co-exist with dissenting views that’s the kicker, I think. It’s sad and alarming that they don’t know this, but that really is the fascist dream. But it’s the liberal nightmare.

Thanks to Jerry Coyne for the link.
