Any clod can have the facts, but having opinions is an art.
-- Charles McCabe, San Francisco Chronicle
I suspect this was meant to be humorous somehow. What I know is that it's about as wrong as can be. Go into any pub, and any clod you ask there will have the most amazing opinions on everything, but very little facts indeed.
In fact the interesting thing is that the really uninformed people often have no clue whatsoever what you are talking about, but they will have formed an instant opinion based on something they were reminded of when you spoke! (About which they also know next to nothing.)
