Passing a message and repeating truth are two different things (as discussed ad nauseum)
If I say I BELIEVE a certain horse at the racetrack will win. That is an unconfirmed message.
If the announcer says my horse didn't win, I don't like that meassge but if someone asks, I have to tell them the truth, my horse didn't win.
THOSE ARE TWO DIFFERENT THINGS.
Please stop being obtuse.
