I take issue with the expression "UX Experts" as you use it. In fact, I deliberately invoke the "No True Scotsman" argument: If someone is an actual expert in the field, they know that what they find confusing is different than what a user finds confusing, and that what they find aesthetically offensive is irrelevant to what works or doesn't work for the target audience/user.

What you are speaking of is the "UX Zealot," exactly as you say at the end of your argument.
