if I were EM I'd sue them back for their absent sense of humour. I'm quoting John Cleese here:
Political correctness “started out as a good idea, which is, ‘Let’s not be mean to people’, and I’m in favour of that despite my age.
The main thing is to try to be kind. But that then becomes a sort of indulgence of the most oversensitive people in your culture, the people who are most easily upset … I don’t think we should organise a society around the sensibilities of the most easily upset people, because then you have a very neurotic society.
From the point of creativity, if you have to keep thinking which words you can use and which you can’t, then that will stifle creativity. The main thing is to realise that words depend on their context. Very literal-minded people think a word is a word but it isn’t.
