Oops, sorry. No, it wasn't directed at you. Sorry, the hypothetical non-journalist.
My point was that the consequences of the transgressions of plagiarism and shilling are relative to whether you're a non-journalist or a journalist, and less so about the actual worldly-impact of such transgressions.
IOW, both you and tptacek are right...but it depends on from what perspective you're looking at this from. Lehrer will likely never get a writing gig as prestigious as the New Yorker, even though what he allegedly did pretty much hurts no one (but the trivial truth).
Another example: in the military, lying about a medal is hugely dishonorable -- the U.S. Navy's supreme commander committed suicide when Newsweek questioned two "valor" pins. But you could be a commander whose decisions resulted in needless destruction/deaths and still get an honorable discharge. The latter case had more actual real-life impact, but the former case resulted in more "punishment" within the group.
