Donald Trump sought to answer a criticism that he was ignorant of Islam, made by the new Mayor of London, Sadiq Khan. Mr Trump’s answer was to challenge the Mayor to an intelligence test, as though intelligence was the same as knowledge. Mr Trump must surely know that a person blessed with a high intelligence does not mean that the person is not ignorant of Islam. His answer was either appallingly dishonest or very stupid.
I do not think that Mr Trump is stupid; I think like many who attempt to acquire power he will say whatever he feels will persuade people to vote for him, that he will blame foreigners for the ills that afflict his nation, or if there are insufficient foreigners he will blame a section of the population for those ills, provided that section is small, different and recognisably so. The trouble is that this approach tends to work.
