I'm not casting any stones, I agree! I bounce the odd landing, but I never accept that doing this carelessly is acceptable. Fly it like you own it, and want it to last!
In my opinion, the only reason to bang a civil plane onto the surface would be it something unexpected occurred in the last seconds of the flare, and getting it down suddenly was the best thing. Otherwise, I think it's just laziness. A couple of more seconds actually flying the plane in the flare, and a good landing would probably have been the outcome.
But then... a good flare is a stall, and I hear that today's new pilots are afraid to stall (perhaps because their instructors were!). Yes, I generalize somewhat, but pilots, fly your plane like it's an extension of you. Fly it so the people who see you flying it say to themselves: "wow, I want that pilot flying my plane!". Fly it so your peers here are proud of the care you take with it - pride in your workmanship!
