Who determines where there is a need?

You?

I use words as I see fit.

This does not at all mean that I have animosity towards you personally. It simply means that the situation induced emotion and passion where the utilization of profanity was an instinctive and fitting action.

You DO exist as a valuable element here. However an opinion need not align with what you in your mind believe yourself to be acceptable or non-acceptable treatment towards an individual in your position.
