Correct. By "oldtimer" I mean older experienced shooters that have been around firearms for a long time and are responsible. The Veteran firearms enthusiast. All sorts of older reckless firearms handlers out there. When the firearm's industry exploded like it did a whole lot of people (instructors included) jumped the shark and went straight to tactical and CCW training because it sells. Fundamentals are important especially when it comes to firearms. The first thing any decent firearms instructor should do with their class or student is have them watch a video of Accidents and damage resulting from poor firearms fundamentals. A lot of them dont have a very well thought out plan in terms of the best way to approach instruction. They tend to gloss over things.
When I introduced my kids to firearms and shooting the first thing I made them watch was all the youtube videos I could find of negligent discharges and accidents at the range. You can tell people about safety all day long but real incidents with visuals make a much bigger impression. Similar to the days of old in Sex Ed Class (STDs) or Drivers training. The style is also used in workplace safety training videos so its not anything radical or new. Trainers/Instructors just tend to be a bit lazy sometimes. Theres a whole lot more to shooting than just knowing CCW laws, presentation and shooting.
At our old range I had an RO sweep me and two of my sons in the parking lot. 20 years retired from the military, extensive collection of guns, certified as a range officer, probably never seen a youtube video in his life. (These were the ROs who were watching our ROs when we were shooting IPSC.) Pulled a gun out of his truck to show me. Pulls out the pistol with his finger on the trigger and sweeps all three of us. It wasn't a might have been a different angle or something. The kids ducked. Guy says "it's okay, it's not loaded."
He knew the rules when there was a yellow and a red line, and God forbid you flip a piece of brass over the berm, or throw trash in a brass bucket. But soon as he stepped off a static firing line, the rules (the fundamentals) went out the window. Sometimes "veteran firearms enthusiast" means he's been doing it wrong a long time. And sometimes the guys "running and gunning with a shot timer" are the safe ones.
As for the training and firearms industry changing- the NRA had to find new shooters somewhere. CCW laws and self defense made sense. As people moved into the suburbs, there were fewer places to hunt or shoot. Governments were restricting guns because of an increase in crime. So yeah, there are going to be self defense or CCW enthusiasts.
I think showing gore in training probably isn't a bad idea in and of itself. I think it works where you're trying to curb some enthusiasm while teaching someone who really, really wants to do something, like drive or have sex. Probably won't work in a class where you're bringing a soccer mom and her kids into a class on gun safety. The decision is going to be that guns are just too dangerous, which is what she thought before she came in. Won't work on a lot of people who are on fence.
As far as Youtube goes, I think everybody on the internet knows 90% of it is BS. When the adults were emphasizing critical thinking in middle and high school in the 80s, it's almost as if somebody knew that we wouldn't all be getting all of our information from 3 channels heavily regulated by the government for the rest of our lives.
