I quite agree and Responsibility to me is to act as expected, in compliance with set rules and if I do screw up I pay for the consequences. Payment may be in dollars or effort...
The same level of responsibility is expected from my peers. Thats common sense.

The base of this discussion is getting shot down in a club enviroment, a place where frequency control must be active.

Lets say I take a $10k jet to a AMA field with frequency board and turn on my tx, shooting down a LT40 trainer which is owned by a 14yr old that saved up all summer mowing lawns. Would I not then be expected to pay him what it would cost to set him up again with a new trainer? Would I be expected to pay based on A) Price of my model or B) It being my fault?

Admitting fault and take responsibility for one own actions is what we grow from, running away from them hiding would run us into the ground. Unfortunately there are too many examples of the latter...
