What’s worrying is that not everyone on Twitter gets this.
Instead Coulter’s ‘effing Jews’ post has had more than 1,500 retweets and sparked the hashtag #IStand With Ann.
It mimics the hashtag #IStand With Ahmed, which was started out of supprt for a US Muslim schoolboy who was arrested for making an alarm clock (his teachers thought it was a bomb) and counts Barack Obama as a supporter The messages contained on its thread are full of love. 'Ann's Army' are using the hashtag to make anti-Semitic comments, inappropriate Holocaust jokes and express their general hatred.
Coulter is the author of 10 political bestsellers, with titles such as How To Talk To A Liberal (If You Must) and Demonic: How the Liberal is Endangering America.
She started out practising law in New York, and is now the legal correspondent for conservative political site Human Events, but spends much of her time appearing on TV shows and writing messages to her 660,000 Twitter followers.
But, perhaps more telling, is that she supports Donald Trump for the upcoming US presidential election.
Coulter is also no stranger to a racist controversy.
Earlier this year she said on Fusion TV: “If you don’t want to be killed by Isis, don’t go to Syria.
If you don’t want to be killed by a Mexican, there’s nothing I can tell you.” She then refused to hug a woman who said she was an undocumented immigrant.
Back in 2007, she told CNBC’s Jewish host Donny Deutsch that she wanted her dream America to be completely Christian.
During a Twitter rant about Republican candidates trying to pander to Jewish voters by focusing on the topic of Israel, she asked ‘how many f***ing Jews do these people think there are in the United States? But in keeping with her Conservative beliefs, Coulter hasn’t let herself get too carried away: she’s starred out the f-word.
Her comments haven’t just been criticised for their racist undertones – they’ve also been pulled apart for their ignorance.
