I get your stance on this. However its best to know when to bow out. I don't gamble, much less risk my life over a sudden test of my priciples. And like the swamp incident the world hasn't changed much evil men still do cowardly, sneaky evil things. Know your enemy and his numbers.
If it where to ever involve family the stakes go up, threatening another grown man is one thing full family is another. Pulling a firearm is just plain "yellow". I had similar event occur on the land I live on. My son and I where ridding and was threatened by hunters who payed good money to hunt.....their ignorant asses didn't know I was married in....they don't hunt anymore.
I've also ran off everything from people dumping trash, to target shooting of all things. Each time I made sure my approach and the deck was in my favor. I carried every time and I wasn't I pussy pointing firearms to get my point across. Its never simple.
The Richland Road thing seems like it's going esculate possibly. I would not go in any single party outings. Multiple vehicles and multiple media recording resources. If the person who got approached could go back, I'd purposely try to get footage or recorded admission of the threats or a similar situation. Then press charges. Get evidence and nail that a hole to the wall.
