The stance against pandering is admirable, but I'm wondering if they would feel welcome? I still remember how hard it was for me to go to the range for the first time on my own wearing slippers and landscaper ear cans, fumbling with targets, and asking the grumpy looking range masters what to do. I imagine for them it would be an extremely uncomfortable hurdle to jump. There are gun shops in parts of American with signs saying no Muslims allowed. That right there kind of cancels out any uneasy feeling we should have about pandering. What's the use of treating everyone equally if they don't show up?
I don't worry about what stores elsewhere are doing. I have no control over them. If you want people to join because you want to use them for some propaganda, to me that's wrong.
Your anecdotal story is not unique to Muslims. It's the same for all new KHSC visitors. There's a lot going on at once, and learning the ropes is not easy if you're on your own.
I took the OGC offered handgun training. That included hands-on at KHSC. I was simultaneously trained, introduced to several handguns and calibers to try, and provided in-person experience on how the range works and the rules.
I mentioned on here more than once there should be a KHSC training resource for new shooters. It could go over all the rules, proper target construction and positioning, types of targets permitted (Steel plates, bowling pins, ...), and the normal RSO commands used.
Maybe someone is willing to produce a nicely edited and narrated video to walk new (and not so new) shooters through all the things they need to know and how to get set up on each range? Post it to the nice KHSC website if possible, or at least link to a video server hosting it. There are a couple of KHSC intro videos out there, but they could be better. Add some "PowerPoint Slides" to list the important rules and safety concerns. Trying to talk on video while filming around live fire isn't the best. Adding the narrative during editing would be much better for computer based training (CBT) videos.
I know there are people here who are professional or skilled hobbiest videographers. Something like this could be a valuable tool for attracting all new visitors who were interested in shooting, but have no idea where to start.
Just a thought.
