I don't recall anyone in this thread being rude to anyone. Robust and disagreeing....yes and as far as I know this is permitted on here and in all walks of British society.
Disagreeing or having an alternative view really is not a crime.
I've been through your posts upthread I would say that there is a fine line here and because we are all in front of computers it's difficult to get over the body language. At least one of your sentences (of many) can be fairly read in the patronising to sarcastic to over-defensiveness spheres. A few other sentence imply that the pilots are in some way failing to do a good job. Not the end of the world, but it can perhaps explain why you are getting some thread pushback even if not so much tug pushback. There again I'm not seeing direct rudeness. Just my point of view.
I must admit my general experiences are quite different from your experiences. Tonight my departure was delayed by 1 hour 40 minutes late due to multiple factors. We were apparently ready to go at 16:30, at 16:37 we had a 2 minute explanation from the flight deck, including the comment that there was a further delay due to an ATC radar desk being closed, and that in 10 minutes he would update us. At 16:53 we got that update (a bit over 10 minutes) and 2 minutes later we pushback. We got 3 further announcements from the front - one mid flight, two after landing. That's an anecdote but very much in line with what I get. I've been on Ryanair services where there may be an apology for the (rare) delay but rarely a clear explanation. I kind of feel that's OK for a LCC, given how little their fares are.
