Political correctness isn’t just about changing the nursery rhyme ‘Baa Baa Black Sheep’ to ‘Baa Baa Rainbow Sheep’; or changing the word ‘history’ to ‘herstory’. It’s also about “affirmative action”, revising curricula (i.e. “canon busting”), police actions and sometimes imprisonments, “no whites allowed” university meetings, censorship, numerous bannings, the “no platform” policy, professors losing their tenure, and so on. (Now add two new kids on the block, ‘safe spaces’ and ‘cultural appropriation’.) In other words, PC has gone way beyond simply changing the words we use.
