I'm hoping the original post is more of a rant & I get it but I guess I'm lucky that when I still went to the public ranges I couldn't shoot good enough to be irritated and didn't have anything nice enough that anyone would have asked. Fast forward a few years and I'm lucky that I'm part of a private club where 90% of the time it is just me and my guests shooting BUT when there are others there I have yet to experience AR15 brass raining upon me, unsafe cold range, or inconsiderate members. Our range rules require ears on regardless if you are shooting suppressed or not and most of the muzzle brake guys make sure the font is out past the firing line and try to make sure there is a bench or two between others. The biggest problem is in fact getting to the range and actually getting my range work in and not talking to much to the old timers either about the rifles they brought or how they reload for them. I try to be as cool to others who haven't made it as far down the long range / reloading rabbit hole as I have because with out new people passing it on shootings sports will not exist eventually, especially with the politics as they are. I've had guys offer to spot when I was having problems at range and step in to help wo/asking when my gear (range finder) wasn't up to snuff. Most of the time there are offers to shoot whatever is on the line from whoever is there. Best group I ever shot was with a gun & ammo provided by that guy with the super cool gun at the end doing load work up. (.17 5 shot group with a 6BR, will never forget that) We need as many people thinking the old Honda advertisement "You meet the nicest people at the range" instead of on a Honda.
This has been my experience at the three ranges I've visited over the last few years.
My thought process is I expect selfish idiots everywhere I go, through example I try to teach them there is a different way to act. Probably doesn't stick 99% of the time but I'm going to keep trying because that way I don't end up irritated and upset with a gun in my hand.
