And we do use the information war tactic in other countries as well, to counter anti-American sentiment, etc., (and article on this @ NavySEALs.com this week)
but the real reason it's problematic?
you couldn't find a journalist that could keep a secret to save your life - now I know you're thinking it's their job to tell us - and most will attempt to claim it is "their duty" to write about that which they know - and of course, all for the "good of the people, though ironically, they have no issue abandoning that same duty in a nanosecond in favor of supporting a personal/preferencial agenda that takes precidence- and the "good of the people" is a lost cause now.
I would suggest further that their inability to keep a secret has not a thing to do with their duty - as is the case for many people, it's simply all about the personal attention it will garner -(and specific to this occupation the career it could make)
and Erika's point - the intentional "discrediting or minimizing by design", so the pertinent/valid point is taken less seriously by those who didn't overtly analyze the introduction of the guest - is that not lying as well?
