The big problem that I have with armchair researchers is the constant litanies as to how "if they had BF in their back yard", they would have volumes of video & pictures, and tons of evidence. They would be rich beyond measure, & anyone that hasn't accomplished all these amazing feats is either "lying, lazy, stupid, insane, inconsiderate, incompetent, not trying hard enough, or all of the above". Then they proceed to ridicule every piece of evidence that is presented.
They're full of ideas, most of which have already been tried & found lacking in the real world. Yet they insist that if their excellent advice had been tried, "this mess could have been wrapped up years ago".
My advice to the armchair researchers is try it before they criticize others' efforts.
