Sir: Dr Graham Gould (letter, 19 March) could not be more wrong about political correctness. It is always about having the power to dominate by controlling speech and expression. Unlike, say, law enforcement, which proscribes certain actions which are deemed to be bad, PC describes certain correct words and deeds, from which any departure is deemed to be bad. Perhaps Dr Gould should reflect a little on the historical use of the word "heresy".
