So, an article by John Farrell is being discussed on Catholic blogs recently? Let me guess: He's causing controversy because of his defense of Catholic theology and/or moral teaching, or his stern criticism of the Cult of Gnu's abuses of science, and he's doing so by displaying he actually is more than thinly informed about the details he's discussing?
Ha! I'm kidding. He's playing Catholic water boy for PZ Myers or Jerry Coyne, right?
Really, I'd throw in my two cents here - but Valicella, Ilion, M_Francis and others have already beaten me to it, M_F being his usual devastatingly effective self about the whole thing. So I'll just do a little fast commentary.
Valicella's endorsement of him aside, I don't take Farrell seriously. He's every bit as much of a combox punk as yours truly, and his main claim to fame is the usual one among a certain class of Catholic pseudo-intellectual: 90% vicious, angry, furious offense against Christians he disagrees with (his specialty: Intelligent Design), 5% mewling pleading with atheists that maybe they kinda-sorta could tone down their criticism a smidge (because there are GOOD Christians too, like, well... Farrell himself! Right? Right? Pat on the head, please, Mister Myers? Brothers in arms, wink wink, nudge nudge?), 5% minutae.
But oh well, at least he indirectly contributed to a worthy discussion by prompting a variety of people vastly more learned than him to correct him on this topic. So at least there is that.
