I certainly believe that, though I think gun trends may also be regional to a degree. Most people in AZ seem to carry autos, but the "gun culture" in AZ is more fully developed and widespread than probably anywhere else in the US, except possibly Florida and Texas.
A small revolver is generally safer in semi-trained hands and good enough for the vast majority of situations Joe or Jane Citizen is likely to encounter. Short-barreled DA revolvers are among the most difficult handguns to shoot well, however. Most people shoot very poorly (slowly and inaccurately) with airweight J-frames, but having one does fulfill the First Rule of Gunfighting.
I would certainly take a small Glock (in .40 or anything else) over a J-frame, but most people aren't willing to commit the training time and money it takes to successfully carry and use a good auto. Thus, they are better off with the safe revolver, which, statistically, they will likely never need to fire anyway.
