Yasmin Alibhai-Brown is Muslim and regards the comment as racially motivated, as well as scary. And sexually motivated, in the sense that he wouldn't have said the same thing to a man, because it's always Muslim women who we hear about being stoned to death.
""Can someone please stone Yasmin Alibhai-Brown to death? I shan't tell Amnesty if you don't. It would be a blessing, really," he tweeted from his iPhone.
Alibhai-Brown said she regarded his comments as incitement to murder.
The journalist, who writes columns for the Evening Standard and the Independent, told the Guardian: "It's really upsetting. My teenage daughter is really upset too. It's really scared us.
"You just don't do this. I have a lot of threats on my life. It's incitement. I'm going to the police ? I want them to know that a law's been broken.""
