Take the following as truth: They, too, can read and write, of course, but their  solecisms,   barbarisms,  and  vulgarisms  call for rebuke, and what better rebuke than to treat them as if they did not belong at all'to condemn them figuratively to the outer darkness of the unlettered?
Then the following statement: "Treating them poorly as if they're unlettered lets us feel better about ourselves and our superiority." is true, false, or inconclusive?
Answer: Inconclusive
