Arrogance at your field?
I think most flying fields are microcosms of life just the same as any other hobby/ activity/ sport. We have our own language, customs and "normal" behavoirs. In life you run into nice people and jerks in the same ratios as you do at the field.
Whenever I do something stupid at the field I usually tend to be defensive at first if someone points it out. I also don't hesitate to to comment when someone does something unsafe as it is my right but I always try to remember how I react and temper my statements to get the point across to a more receptive listener.
I find the newbies often welcome constructive critisim as they want to learn the local customs to be able to fit in and not get singled out for being unsafe.
If you landed in the pits, I would be very concerned. If you took my saying something about it personally, good. Learn from it and move on.
