Frankly it's more surprising that a respectable publication, even a right-leaning one like the Wall Street Journal would think it's a good idea to wade into the religion/science "debate" even in its opinion section. Of course it is irresponsible for a newspaper to not publish articulate expert-authored responses to an opinion piece, newspapers have a responsibility to publish responses written by more-famous and more-qualified persons when the response meets the paper's basic standards. But the WSJ is owned by Rupert Murdoch so I can't say this is a particularly surprising lapse of journalism. (This is hardly first time their editorials have been accused of deliberate bias imposed by the paper, over and above the author's opinion)
In defense of the WSJ, they do seem to keep their bias to the opinions section, which is the appropriate place for it after all.
More interesting will be seeing what the long term effects of Murdoch's influence does to the paper's reputation; in the extreme case it may turn out like Fox News (also owned by Murdoch) and become a punch line to anyone who isn't among their readership. Though I think it's more likely they will successfully navigate the slippery slope, and maintain their position despite having these minor scandals every year or so.
It's a bit depressing, since the editorial in TFA and all their climate nonsense are counterfactual in the fairly literal sense of ignoring and misapplying science and logic in a way that could nominally support any conclusion whatsoever. A newspaper of the WSJ's former caliber should and surely does know better, but such is the state of the american press in 2015.
