Who says what is correct? Where does political correctness come from? In most cases it comes from some middle class academic, or product of academia. Historically there has been a pre-occupation with correctness. This correctness has in many cases been prescribed by academics. The right way of writing. The right way of arguing. The right way of thinking. These academics are self-serving and self-perpetuating; they reproduce what they have been taught and thus maintain the status quo in what is acceptable. To offer alternatives to their notions of correctness would put them out of a job.
