We have fleas!
Fleas? Why fleas?
Richard Dawkins's response to theologian Alister McGrath's writing a book called "The Dawkins Delusion?" was to quote poet William B. Yeats about his imitators:
You say, as I have often given tongue
In praise of what another's said or sung,
'Twere politic to do the like by these;
But was there ever dog that praised his fleas?
Note how several of the authors have imitated not only Richard Dawkins's title, but also his cover art -- and how Sam Harris has also gotten that treatment.
The first one has a few YouTube creationist videos, but not much else, while the second one is much more active.
