Yes, I say you're being irrational. Unfortunately, these days country of origin does not equate to quality (or lack thereof). Case in point, Vortex's Razor HD binos. They're made by the same company to the same spec as when they were in Japan, the OEM just moved production to their China facility. So just because the factory is located in China, the company fabricating them is based in Japan.
Leupold is "MaDe In ThE UsA" but there's probably as many or more Chinese components in their products as any other brand (Notice their tagline is now "Designed, Machined, Assembled in USA") I've been grossly underwhelmed by EVERY Leupold product I've owned and had experience with, from binos to scopes to rangefinders to spotters and everything in between. Their eyecups suck IMO, I don't like their color rendition through their coatings, and their electronics warranty is amongst the worst in the industry. So I look elsewhere without thinking twice.
As a matter of fact, the most catastrophic failure I've ever had in a scope was on a $1k VX5HD. Was murdered by the recoil from a Howa 1500 in 7 Rem Mag, quit tracking fairly fast. Also ended up with a spiderweb crack on an internal lens for no reason. Put it in the safe and it was fine, pulled it out a week later to go shoot and it had a big crack across an internal lens. Nobody gets in that safe but me, so why did it fail? Leupold scopes are notorious for wandering zero. I'll never own one again, unless I get a hankering to chase my tail for fun.
Realistically, a move from Vortex to Leupold for all other pieces of glass is more of a lateral move and based on personal preference. Personally, though they've never left me high and dry, Leupold's customer service has always been SLOW and inefficient and at time accusatory and questioning (are you sure you did this right, are you sure it's broken, etc.).
For riflescopes, I've moved to SWFA 100%. My other gear is largely Vortex because it works for me and mechanical devices can and do fail, and I like knowing that when they do a company will stand behind their product for me. I don't have faith that Leupold will do that as efficiently as Vortex will, so I own lots of Vortex products (except their scopes).
I currently run Vortex's 10x50 UHD Binos, a Viper 20-60x85 Spotter, Viper 3000 RF, and a Diamondback 15x56 Bino for tripod work when needed. Wife uses their Diamondback 10x42's and they're great for her. My backpacking tripod is also a Summit Carbon II with a Slik SVH-501 Fluid Head swap. I'm not necessarily brand loyal, but I find that Vortex offers a ton of bang for the buck for my uses so I do use lots of their stuff.
Leupold is stuck in 1985 as far as I'm concerned, and their expired in 2010-ish military contract isn't enough to keep them relevant in 2022.
Long story short, yes I think your move to Leupold for your listed reasons is short sighted. Now, if their optics fit your eyes better or there's a legitimate reason otherwise, then I say go for it. But if it's just for country of origin, my advice is to do a bit more research before you throw the baby out with the bathwater.
Oddly enough, Lots of Leupold's and Vortex's stuff is made by the same OEM manufacturers. The Vipers and SX-4 spotting scopes are the EXACT same scope, just built to whatever company's spec is that wants their logo on the side. The Razor and SX-5 really are identical, go lay them side by side at your local optics counter and you'll just shake your head. There's more in common with them than you'd think, it all comes down to ergos and coatings and... customer service. Leupold falls behind on all 3 for me, but especially their CS.
But hey, I'm just some random guy on the internet...
