Are you looking at this thing from an 'All Round' aviation perspective or just from the Commercial point of view. I have seen and sent round student pilots who were never going to make the runway unless it were 7 miles long - they were that hot and high. Now although I agree with your comments aboout 'division of responsibilty' there comes a point where you have to say something because as well as the pilot killing himself or damaging the aircraft it's also our livelihood on the line. My licence is my living - and no person's going to risk that.
Nobody ever got hurt from being sent around - but believe me, it's not a decision we take lightly. If it's done it's done for good reason, and because it's OBVIOUS that the guy has got it wrong.
As has been hinted before you do your job and I'll do mine - part of mine is keeping that runway open and not having a ball of metal rolling down it in bits and flames
