If we're looking for who comes out with the most brash, unsugarcoated, unapologetic, don't care what anyone else has to say?: Navaros, hands down.
The thing is are we talking about expressing their opinions honestly no matter what anyone else cares or are we talking of intellectual honesty here? I f its the latter then Indeed it would go to such as Lemur or yourself Don. Their are many others I can think of. I am another who many times just says what he thinks off the top of his head. Many a time I go back and think to myself "maybe I shoulda thunk a little more before I posted that" Is that honesty?
