It's also a sign of intense hubris - the idea that thousands of labor economists have never considered something they thought of after 30 seconds of reading means that either a) the economists are all idiots or b) the reader is orders of magnitude smarter than them.
The communications from the BLS are quite good and easily understandable. The problem is that the people making these complaints aren't reading those, they're reading the mainstream reporting on the BLS stats, which is extremely lossily-compressed, and then assuming this makes them qualified to criticize the underlying stats. Journalists deserve some flak here for the superficial way they report on the numbers, but at some point it's on you to get the real thing before you start trying to correct it.

One thing is for sure is that people aren't going to do that.
Anyway, it seems disingenuous (or just completely irrelevant) to complain that people are attacking the BLS rather than how this is wielded to perpetrate a polemic.
My point is one doesn't have to go to the original sources, they simply have to ask themselves "is it likely no one has thought of this before?" before launching into a criticism...
