My basic sympathies are with PZ. I’m in favour of occasionally having a bit of harmless fun at the expense of the religious as long as there aren’t too many obviously foreseeable adverse real-world consequences. In other words, I’m basically of the view “it’s all fun and games until the Danish Embassy gets burned down”.
On the other hand:
… Dawkinsite militant atheists are as annoying as fundies in their own way and perhaps deserve a bit of winding up too. Thus I have determined to strike a blow in retaliation on behalf of the Catholic Church.
… I plan to tell a small, credulous child that a rainbow is a special sign from God that he promises never to flood the world again and that this proves that God exists. And PZ Myers will have this on his conscience … as a direct result of his actions.
Heh. Take that, asshole.
