Whereas I certainly have confronted my share of idiots in campgrounds (let me rephrase that, people who think the rules are for everyone else), I really, really try to refrain from it these days. One thing is that you just never know just how crazy that group may be. Here's something to consider. If the verbal confrontation escalates, are you capable of defending yourself in such a way that the whole thing will look to a court of law like you had no other choice? As an ex-martial arts instructor, I am very confident that I can more than defend myself. (At my level I used to routinely spar against 2-3 black belts at a time. Sometimes with the guys having weapons.). That very training is very likely going to put me at a major disadvantage when dealing with law enforcement & the current judicial system. The last time I confronted someone, it was coming to the rescue of an older guy whose wife had gotten into a verbal altercation with a group, when campground security failed to show up after repeated calls. I was able to calm things down, but purely by sheer intimidation. (I later filed a written complaint with this private, highly rated, So Cal park, documenting that their security had been negligent, documenting in writing that I wasn't the instigator.) The next time I was in the same park, my absolute last time ever, the same group, with a few additions, were a few sites down from us. They kept looking our way & glaring. I fully expected that after a few beers they'd come by for a visit. I walked down & negotiated a truce. Good thing. I was told that they were planning to vandalize the rig that night & then leave real early in the morning. Any true martial arts guy will tell you two very relevant things. First, it is to be used only for self-defense. The second is that the very best defense is to not be there.
