Well I am a sportsman and a shooter not a redneck from the woods. I know what is on the end of my barrel and its only right to warn anyone who is around when I am shooting it. If I turned it around I would be pissed too if someone unloaded 5 ft from me without warning.
See, I could deal with that and have a good shoot with someone like you. Unfortunatley people like you are few and far between at public ranges.
