I wouldn't say the Pax comments are unwelcome, just pax comments that are judgemental without having the full facts. We certainly try at all times to fly in a way that does not alarm the passengers (bank angle, smooth pitch movements etc), but I think that droopy's comments stuck in the craw because he was claiming that because of his 'expert' background, his observations from the back were more valid than another non-airline slf. I would be more than happy to defend/justify/explain if the observations/questions are not phrased aggressively.
