That smacks of the famous "you don't know anything about (insert sports here) because you never played the game."
The role of any media professional is as a translator. We're there to explain complex issues or topics in a way that informs and enlightens people who don't know anything or little about the subject.
Hopefully, we sift through the information and turn jargon into actual English words. I don't have to have chalk dust and carabiners in my pants pockets to write about rock climbing. But I do need to ask the right questions if I'm trying to describe the context of an historical event and use the correct terminology.
The ball got dropped somewhere along the way, and of course, today's technology (and reliance on content aggregation) just compounds the misteak.
If you do your homework and ask the right people, you can write or speak intelligently about nearly any topic. I took Basic Auto Shop in high school, but all I needed to do was to ask very specific questions of Doug Yates to help explain exactly why fuel injection was a big deal for NASCAR.
I didn't have to tear down the carburetor myself. (Although when I did in 1975, I somehow ended up with a couple of springs and two small screws left over.)
