To discuss it implies that it comes into question, that it's a matter of choice to be technically competent in what one does.
The "nice shoes but incompetent" contingent isn't that way because they thought, "Hmm, where should I be on the competence continuum? Competent? Incompetent? Gosh, incompetent sure sounds neato." No one chooses to be an idiot, and it's those who don't know they're idiots that are the most dangerous.
On the other hand, shoes and attitude are always a choice, and there are many possible acceptable ways to go. This is a thread about those matters that *are* up in the air, not those that go without saying.
Raising the point you raise won't give any useful information to anyone who isn't an incompetent idiot (and by raising it you imply that maybe someone here is one, which is part of why my hackles are up), and unfortunately it wouldn't set any incompetent idiots on the path to righteousness either because the biggest problem with incompetent idiots is that they don't know they're incompetent idiots, so they never recognize themselves in such words of warning. So you've accomplished nothing (other than keeping me moderately entertained on a slow morning).
It's kind of like if someone posted asking for driving directions from New York to LA and you give a lecture on proper use of turn signals. Irrelevant and condescending.
