Not all passengers are sinners - but not all cabin crew are saints.
Yes but is a packed aircraft on a tight schedule the right place to argue your point ?
No. So either disembark or just shut up and do as you're told and write an angry letter to Customer Services after the event if you feel hard done by.
The reality is that all you're doing by giving the crew a piece of your mind is pissing them off. The added benefit of following the established complaints procedure is that your complaint gets looked at by a second pair of eyes and possibly even gets resolved for the long term (i.e. words with / retraining of / disciplining of crew involved)....by trying to DIY with the cabin crew all you're going to get is an ultra short-term resolution that will only last as long as the duration of the flight... nobody in HR or anywhere else will hear about it.
