My whole point is to avoid turning this into right or wrong by realizing that an accent or a bias merely describes a particular way of speaking or thinking, not a degree of deviation from some standard. In linguistics, this is the prescriptive vs descriptive debate. It's not controversial that a prescriptive grammar declares how a language should or ought to be used. Declaring one accent the standard is a similar prescriptive position.
