And of course you’re not allowed to question her since she has a masters.
I ran into a similar problem with a club member last weekend. Well, I guess "problem" is a bit of an overstatement. It was just a couple of rude comments, but I was troubled by it nonetheless.
To summarize our exchange: I mentioned that I admired the work of Nick Lenz and other unorthodox growers in part because they expanded the conceptual space of what we consider to be bonsai. By pushing the boundaries of bonsai as an art, he and others have widened the field and given us humble hobbyists more room to play, so to speak. The aforementioned club member told me I was "acting arrogant" because he knew Nick Lenz, spent time at his garden, and owned four of his works, and I didn't, so I certainly wasn't qualified to talk about his work.
Setting aside the hypocrisy of that statement, I don't think that kind of (mis)behavior is an issue unique to the bonsai community or even to the broader gardening community, but, as you implied, it seems to be an issue endemic to the human condition. You weren't allowed to question the expert because you weren't qualified. Yet, a degree isn't meant to be wielded like a stick. On the contrary, it's meant to signal you know better.
