Yeah, I would attribute that to tribalism. There's an intense amount of dogma in the Kubernetes community, likely stemming from the billions of dollars that get fed into the ecosystem by Big Tech. I genuinely think people adopt it as part of their identity and then become hostile to anyone who "doesn't understand the excellence of Kubernetes." I only say this because I've had many lunch time conversations with random strangers at the various KubeCon conferences I've attended - and let's just say some were pretty eye opening.

I would also say that a lot of people, even people who are professional k8s operators, don't understand enough of the "theory" behind it. The "why and how", to put it shortly.

And the end result is often that you have two tribes that have totally incorrect idea of even what tools they are using themselves and how, and it's like you swapped them an intentionally wrong dictionary like in a Monthy Python sketch.
