Yeh, I said it, and I mean it.
Grammar is the internal logic of a language. Deriding those who espouse good grammar and point out bad grammar is equivalent to deriding logic, indeed reasoning.
Most who vomit up stupid comments about “grammar Nazis” also claim English is inconsistent and illogical in its grammar and, indeed, in its spelling of words, massive numbers of words that either look (when written) or sound alike but mean different things, etc. *meh* That’s either because they are butt-lazy illiterates or want to encourage butt-lazy illiteracy for their own nefarious purposes.
Understanding the internal logic of English (its grammar) requires something more than a “literacy” comprised of the ability to laboriously puzzle out what words those funny lil squiggles are and assign (often incorrect) simplistic meanings to them; it requires the reading of a lot (no, much more than you think “a lot” means!) of well-written text, an interest in what the words in that text actually mean or meant when the writer committed them to paper, and a cultivated ability to actually think.
Those three conditions are not met by at least 99.999. . .n% of the Mass MEdia Podpeople Hivemind who are the primary corrupters of English nowadays. Let one very small example from a CNN chiron this morning stand as a typical example. Referring to Robert Mugabe of Zimbabwe:
“. . .his own party said they will move to impeach him if he didn’t [sic] resign by the deadline.”
When someone cannot even keep past-present-future clear, one is safe to assume that that “someone” is a self-made moron. And such is the nature of the influence on the English language that the Hivemind exerts: teaching a-rational thought processes, by inundation with example after example.
