Stupidity and evil are the same, if you go by the results.
That's the admirable Margaret Attwood, from 'Surfacing'. She's most recently been in the news for boycotting a literary festival in Dubai which banned a book with a gay character.
We've recently learnt that she's the hero of Caroline Lucas, Britain's first ever Green MP, having recently been elected for the Brighton Pavilion constituency, and a potential backer of a mooted progressive government.
Unfortunately, though, there's more to Lucas than you might guess: she's a signatory to this letter, one of the more stupid/evil bits of writing I've seen in the papers this year.
(An example of an intelligent/good letter, largely from a different corner of the left, can be found here.)
