As Rosie says, this kind of anticipatory censorship will have its greatest impact, not on western writers like Ophelia and Jeremy who view Islam from the outside, but on 'those who write from within - the liberalisers, the reformers, the feminists, the novelists, the historians. They will write and no one will dare to publish them'.
Does God Hate Women? was due to be published on 4th June and it's available at Amazon, so I assume Continuum recovered their courage at the last minute. You can order the book, and support the freedom to criticise religion, by following the link below.
See Rosie's comment below (and the updated post on her blog) for clarification of what actually happened - i.e. it seems the whole controversy was stirred up by the Sunday Times, looking for a sensational story. It doesn't change the basic point: journalists (like politicians in the Wilders case) now assume that there will be a 'backlash' against any move that 'offends' Muslims, and rent-a-quote fundamentalists are always on hand to oblige, thus creating the very outcry that the media has anticipated.
