18-Wheeler, lighten-up dear chap; this is a discussion... not a "slagging forum".
The perceptions of right or wrong are variable... especially within PPrune!
The playing of mind-games with other members of the crew doesn't promote good CRM. If you had a continuing problem with your F/E and that a chat over a beer couldn't resolve your percieved issue then go and see your Flight Manager to resolve it.
I'm with Old Fella on this one... it was wrong of you to attempt to "bully" your F/E into submission; besides which... given that he was now at the rear of the flight deck he was now totally out of the loop with respect to any take-off emergency (would you still be "grinning" if you'd encountered a problem?).
Having "stood-up" the thrust levers (throttles or whatever you wish to call them) you've theoretically proved that one (or more) of the engines aren't going to significantly lag. Therefore, after the call of "stable"... any lack of engine response to thrust lever advancement should then be cause for a "Stop".
Happy landings
