Mick Hartley declares Eagleton's latest attack on Dawkins, Amis, Rushdie, etc., a disgrace. Martin in the Margins has a bit more to say, including this:
"If you can get your audience to see your opponents as part of a wider, sinister movement - the war on terror, neoconservatism, late capitalism, imperialism - this relieves you of the necessity of engaging with their arguments."
Unfortunately, that's pretty close to Eagleton's style of argument.
There's also some good discussion going on over at Butterflies and Wheels.
