Summary: PZ Myers has created a “rude” environment on his blog, where the emphasis on ridicule and insult can obscure the nuances that separate good scholarship from pseudo-scholarship.
[EDIT– It has been pointed out to me (see comments) that some of my generalizations in this post are unfair. I agree with the assessment. My comments below are motivated by a particularly bad experience in which I was heckled by a few participants, one of whom trotted out some literature from a holocaust denial publisher, which left me somewhat enraged. In this specific experience, constructive discussion was simply unable to gain a foothold amidst the cacophony. This does not change my critique of Pharyngula’s general style as a community, which echoes (and amplifies) the style of denunciation and ridicule that appears in PZ’s own writing. I don’t think this style is a good representation of science and it interferes with the mission of public understanding.]
