@ChrisJWilson you make a couple of good points. I didn't follow the debate all that closely (I only learned about it from reading his post), but I think it developed more after he wrote his blog. I also agree that it's a natural tendency to be more or less amenable to certain ideas by their grouping — it can be a helpful abstraction, but also a deceptive one. I guess it just requires discernment on a case by case basis to determine where to put one's interrogative efforts.
