I was absolutely right, the letter has been defended as "great satire on the silliness of Political Correctness."  The writer does, however, make a good point acknowledging that using diversity to describe Donald Trump's values is the height of satire.  However, the satire is not "on the silliness of Political Correctness" is on the idea that there's anything in Mr. Trump's values which supports diversity.    If I were to construct a satirical candidate who represents virtually every bias and prejudice available he or she would be Donald Trump.
