“Political correctness” is a treacherous ideology, which can turn you upside down. I avoid the term if I can because it has a double meaning. On the one hand, it describes a liberal and in my view admirable campaign to persuade institutions and the wider population to treat people equally regardless of gender, colour or sexual orientation. Like all campaigns in democracies, it can win only by winning arguments.
But political correctness has become a despised term because it also means the silencing of arguments.
