For many years now, the most popular poet in America has been a 13th-century mystical Muslim scholar.
Translations of Mawlana Jalaluddin Rumi's - better known as Rumi - verse are hugely popular and have been used by Western pop stars such as Madonna.
Well, that's news to me and I suspect to most Americans.
I would guess that the most popular poet in America (if he can be called such) is Bob Dylan, but as far as proper poets are concerned William Shakespeare is unlikely to have been knocked off his perch. If we are talking about poets who lived in America then Robert Frost would be my choice, though others would vote for Walt Whitman or Emily Dickinson but remember Longfellow and Poe and countless other famous names. Of American born poets, TS Eliot is something special. Trust Al-Beeb to chose some obscure Muslim.
Visit the Rumi entry on Wikipedia and you will find that all the poems and sayings that are critical of Islam have been labelled as 'not by Rumi' but by an imitator and falsley attributed to him!
