I believe that "live and let live" vs. "there can be only one" is an axis of difference as important as left vs. right or authoritarian vs. libertarian (with which it's weakly correlated). In that context, I'd say there are probably insecure prescriptivists on both sides of this particular fence, riling each other up. "Meat is murder" is the exact mirror image of the Bourdain quote that leads off the column. It's generally not persuasive, and often not meant to be. While it might actually be true in some sense, its purpose is often to demean and demonize those who make a different choice. Just as left and right sometimes forget their principles in their zeal to troll each other, so too do cyclists and car lovers ... or vegans and BBQ lovers. This article is no more than such a salvo.
