premise: 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 and true is true and true is true and true is true and true is true and true is true ?
hypothesis: They can read and write , but they are n't exactly polished , so we treat them as poorly as those who ca n't read and write .
