I'm generally confused, being old and all, but this one is a repetitive sort of confusion. Happens every day, apparently.
Let's say Joe knows just a bit of muzzleloading, is excited about it, is just getting into it. He buys a really nice, functional, accurate mass production gun with no close resemblance to anything ever made when black powder guns were the latest modern invention.
Joe then asks Bill, a guy who has dedicated a lot of years and resources into developing a historically authentic outfit, whether or not his gun is authentic or Period Correct. The correct answer is no and Bill says, "It really isn't authentic nor representative of guns from any particular period."
Joe is insulted and feels Bill is being a snob. Bill didn't say, "You're a rank beginner, you know nothing, I am superior, you are not welcome around here." But somehow that's what Joe thinks Bill said, and then Dave and Ken say, "Yeah, you guys are nazis!"
Huh? Why does Joe need to feel that as a beginner, just getting into the sport, he has automatically bought into the whole re-enactment thing? I find that if Joe decides to stick with his superbly accurate, highly reliable, fun mass produced rifle for years, he then gets even more adamant about "purists" being mean-spirited people trying to rain on someone's parade. Why is that? Nobody is stopping him from participating in a shoot, or preventing him from hunting and enjoying himself. Maybe folks don't understand that re-enactment is a different level, a whole different animal entirely.
Let's switch to cars. One guy has an old Chevette, the other a vintage T-bird all tricked out. Does one guy have more or less of a right to the road? Not. But at the vintage car show, would it be right for the guy with the old Chevette to get all indignant if the folks running the show don't want him to park in the front row? Would you expect to have a spot on the front row of a classic car show with your current ride? Looks like the same sort of "entitlement" attitude to me.
I have the authentic guns and am waiting till I get the rest of my outfit together before participating in re-enactments. I would not think of going and putting someone in the awkward position of telling me, "We're trying to portray history accurately to the public- and your clothing is just not helpful for what we are trying to portray."
