As I've worked in the public schools and taught classes in higher education, I've been baffled by the fact that the average person does not know how, or simply does not choose, to use good grammar. I've graded numerous papers in which I've explained that slang terms are to be used sparingly and only under special circumstances, there is no place for profanity in a professional paper, it's a good idea to choose one narrative mode and stick with it throughout the paper, and subject-verb agreement is a necessary component. It always surprises me that I'm explaining these things to college level students (sometimes grad students, but those are usually not native English speakers, so I grant them a great deal of leeway).
Then I stumble onto things that cause me to say, "Ah-hah!"
