Is anything a birth right?
Well put Bymonek.
The self inflicted paranoia of FO's approaching command is a reflection of their readiness (or lack of) for command. Yes, there are a lot of mistruths thrown around by a few trainers and line pilots alike which clouds rational thinking if you allow it. Part of any position of responsibility is to sort the wheat from the chaff and if you don't have the maturity to do so, then you aren't ready for the step up. If you can't phrase a perceived difficult question so as to not upset anyone, how will you deal with an FO/Purser/Engineer/Cabin Crew that is off on a tangent or will you chose to 'stay below the radar' again?
Message to FO's, grow some balls and stop running away from shadows.
