Like someone who has never been a licensed aviator who tries to advise
current aviators on navigation aid functions and techniques.
Like somone who has no training, certification or licensure in ANY
healthcare profession trying to one-upmanship those who are.
Let us not forget those who have attempted to embellish thier military
service record with the sacrifices of Soldiers who were KIA three years before
the commenter was ever IN the military.
And there are those who make scathing comments on the nature and character
of various volunteer organizations although they themselves have never been in
any of these organizations, and in one case where they hadn't even reached
puberty when they made thier "observations" on those organizations.
