A day or two ago, someone with whom I have only occasional contact online felt the need to share with me a link to an article about a study supposedly proving that ‘grammar Nazis are mean and have no friends.’
My immediate response was, “I had no friends long before I became a professional grammar-fixer.”
Motivations of the link-sharer aside, the person who wrote the article made the mistake of equating ‘person who goes around pointing out all errors in grammar and spelling and punctuation in social-media posts and face-to-face conversations’ with ‘person who knows a lot about grammar and spelling and punctuation, and gives useful feedback WHEN ASKED.’ I totally agree that a person who insisted on correcting everyone else’s grammar all the time would be extremely annoying, and not only to the person whose grammar they were correcting. (Bonus idjit points, though, for those who incorrectly “correct” grammar, etc.) On the other hand, I suspect I’m not the only person in the world who knows damn well that irregardless isn’t a word and yet never corrects those who use it in ordinary conversation.
If you believe that merely knowing a lot about the mechanics of writing causes a person to be mean and unlikable, you have a problem. Maybe you had a Bad Experience involving an incompetent magazine editor when you were young and easily discouraged. It happens. That’s no excuse, though, for equating ‘knows how to diagram sentences’ with ‘is evil and kicks puppies.’
