Ok, i read the thing. First off, it's long and dry.
That said; no one should ever try to escalate an arguement like that! How drunk or just stupid did the other guys ahve to be? If someone were hunting on the land at my family's farm, I would simply send my sister to ask them to leave. That's just because no one is gonna feel threatened by her. I'd tell her to be very nice and polite. I would then, at the same time, be prone and making use of my scope. It's not that hard to get along folks! If someone was dumb enough to yell and swear or use slurs at/on me (and i do mean a stranger here) and did it in a threatening way, i'd punish them. I'd punish them and any one of their friends that's watching and didn't stop them.
