So... why single out Whole Foods and compare them with creationists?
Because it works, for the most part. It elicits an emotional response in readers who have an irrational hatred for people who happen to ascribe to creationism. Like most "editorialisms," it's a race for the bottom.
If this is the kind of crap Slashdot is going to keep posting, maybe it's time to go elsewhere.
I quit reading Slashdot regularly about a year or two ago for this exact reason and started reading HN instead. Unfortunately, I've noticed that the left-of-center outgassing from Slashdot and elsewhere has caused many of these other sites to express the same symptoms within a short few months. The tech community is, at large, an echo chamber of Leftist ideology and ideologues who suffer from various degrees of disdain, disgust, or hatred for any who holds beliefs that run counter to majority views. Any suggestion that minority opinions may be welcome is a ruse.
Watch my comment for illustrations to this effect; within a few days, it'll likely have replies confirming my suggestions by denigrating common scapegoats for societal ills (the "extreme right," global warming "denialists," religious believers, etc.) painting them as the most vile of scum. Or observe the sibling comment just prior to my posting that illustrates the condescending pretentiousness that is endemic to these discussions.
My motive in leaving Slashdot was the fault of vitriol I observed directed toward those whose comments I've enjoyed over the years (and friended them). It was depressing, to say the least, and reflected poorly on the Slashdot community. So, packing up and leaving for a while seemed the only option. Except that it's inescapable. You cannot go anywhere without encountering this sort of vitriol. Maybe it's the fault of society in its present state, maybe it's the fault of Internet discussion and what behavior it encourages. I don't know.
Fortunately, with the libertarian revival as of late, I've noticed some Slashdot threads improving in balance. Or maybe it's because of how I left my thresholds configured to filter out mostly the people I enjoy (who are still posting, thankfully).
