It's not atheist-bashing, actually. It is a critique of one, particular, evangelical, atheist movement led by Dawkins and co.
Dawkins and co seem to be the fundies of the atheist world, devoting a lot of effort to attacking religion, and exporting their ideas that religion is ridiculous and damaging extensively via the media. I think
@JustGeorge 's uncle is spot-on when he observes that they've made a religion of it!
I have no problem with atheism in general, or with the physicalism the New Atheists espouse. It seems a perfectly reasonable point of view to take. The principal problem I see with New Atheism is that it attacks religion without seeming to understand what religion really is about. Thus it spends most of its time vigorously attacking a caricature. The focus on demolishing biblical literalism (what, again?), which is just a naive c.19th invention of a handful of Protestant sects, is a case in point. More generally, it seems to make the error of thinking religion is about giving an account of the physical world, rather than understanding that it is first and foremost a guide for living one's life.
And, since the New Atheism spends its time attacking religion, it can hardly object that religion may attack it in return.
