Talk about leaving out relevant information. Well yes, Christianity has certainly been a huge influence on Irish culture for centuries, but that hardly tells the full story. Making that vague statement without pointing out that two brands of Christianity have been murdering each other for much of that time is a lot like whitewashing the truth.
That's exactly like Dawkins warning that religion provides a structure for people to divide into opposing camps, define themselves by membership in a camp, and kill the members of the other camp. It would be a one-sided argument if taken out of context, but not if used (as by Dawkins and Brayton) as a counterargument to the dominant/prevailing/background argument that religion benefits the community. As Brayton points out, it is a necessary part of the whole truth.
I am glad to see Brayton arguing like Dawkins because I think he made a mistake when he declared himself to be a member of... well, the opposing camp:
I am firmly a member of the first group, as are the vast majority of those I work with on this issue. Genie Scott, Rob Pennock, Wes Elsberry, Nick Matzke, Jack Krebs and nearly everyone I consider colleagues in this regard recognize that the dispute is over evolution and creationism, not over theism and atheism. But some, like Larry Moran, PZ Myers, Richard Dawkins, Gary Hurd and others, are involved in an entirely different battle. For them, it's not enough to protect science education from the attacks of some religious people; religion itself, in any form, is to be attacked and destroyed by any means necessary.
I thin Brayton's self-classification is a mistake not only because I tend to think that Dawkins has the better arguments than the "appeasers", but also because Brayton - much like Larry Moran or PZ Myers - is temperamentally not suited for charming the religious, so he can be more effective if he doesn't try. He is quick to call some types of religious arguments idiotic, and he is usually right, but the division among anti-creationists is not about who is right (they all are), but who is diplomatic. And Ed is not diplomatic, which, BTW, is one of the reasons I read his blog.
UPDATE: Ed Brayton responds here.
