Is it? When I moved to Houston 15 years ago American shooting center (huge range, clays, long range, etc) was a bunch of guys that look like me (now). I go now and on a Tuesday afternoon and its 50+ Asian men with nothing but tactical SA rifles, and maybe 5 old white dudes working on some handloads. Every. Single. Time. Pistol range about 80% Asian and Hispanic guys that was 90+% white guys from Katy a few years ago. The entire clay section still has the same demographics, along with the 200-600yd (or whatever it is now) long range stuff. Mostly middle aged professionals that trend white male, although there is more women showing up at the 5 stands everyday (including my wife)
So, while it seems the tacticool trend bothers you, both sales and what's at the range seems to be getting more and more mainstream. Shit, I see just as many chassis rifles as I do wood stocked hunting rifles. Good luck seeing anything with custom exhibition wood on the rifle range, maybe 1 out of 10 trips - it's typically mine that some old guy will come ask to take a look at. Chassis rifles are "tacticool". No one is committing crimes with them. Why is precision shooting tactical? Are you yearning to go back to the 1.5 MOA out of the box model 70's of our youth? As long as it can hit a dinner plate, remember that? I'm looking at replacing some shot out barrels on my hunting rifles with a carbon fiber barrel. Is that tactical, or just modern tech.
Remember when you didn't know anyone that hunted with an AR? Forget about shooting sounders out of helicopters for a moment. 90% of the kids you see on facebook next to scraggly spike or fork horn have a little 556 with the stock completely collapsed, and a can on the end in the pic. Turns out super ergonomic (will fit kid 1, 2, and 3 perfectly with the pull of a lever), affordable, indestructible, low recoil rifles are popular with people with small kids. Oh and I can make it where their little ears are protected too, sign me the fuck up. No more trying to unfuck a flinch for a decade after handing your 10 yo dad's '06 because you want to get your kid involved in hunting. Now, lets talk about mowing down sounders. It's fun af. Does it bother you that people enjoy that?
First time ownership of firearms is record breaking year after year, and across every demographic. I would bet both aisles are well represented in that rainbow coalition demographic spread. Prices are up year after year due to demand. Exciting new wildcat rounds showing up every other year. All of that screams mainstream, and I'll bet dollars to donuts those first timers aren't grabbing some easily accessible plain walnut ADL, and certainly not some AAA Claro adorned Blaser. Doesn't bother me in the least. Less competition for what I personally like to fill my safe with.
