I recently found out the preferred pronunciation of the word "quinoa" is KEEN-wah. Now I have to decide if I'm actually going to say that in public.
That's the thing about learning esoteric information: when you begin to use it, you become a pedant in the eyes of the layman. It might not be "Van Gouchk," but it's close.
It turns out I spend a lot of my life wanting to avoid looking like characters from 1970s Woody Allen movies.
Correct apostrophe usage is another of these issues. How hard is it to add an apostrophe and an S to ALL singular nouns, irrespective of their spelling? The common man's inability to follow fifth grade grammar makes me look like a jerk.
I recently had a talk with my daughter about some aspect of commonly-ignored grammar (I forget which one because there are so many) and I had to tell her, "Now you're going to have to decide whether to speak correctly and have everyone think you're wrong, or speak incorrectly even though you know it's wrong." Since she's homeschooled, she didn't even begin to entertain the idea of being intentionally wrong. But then, she's still got a lot to learn.
