Sarah Palin’s daughter used the word ‘faggot’ to attack someone who criticised her mother.

Willow Palin, 16, told a Facebook friend that he was “so gay” and used the homophobic insult after he criticised former Alaska governor Mrs Palin’s reality TV show.

According to TMZ, Willow attacked a boy named Tre after he posted a status update saying “Sarah Palin’s Alaska is failing soo hard right now”.

Willow retorted: “Tre stfu [shut the f**k up]. Your such a f**got [sic]” and “Haha your so gay. I have no idea who you are, But what I’ve seen pictures of, your disgusting [sic]“.

Her older sister Bristol also joined the row, writing: “You’re running your mouth just to talk shit.”

When more Facebook users joined the argument, Willow wrote: “Sorry that you guys are all jealous of my families success and you guys aren’t goin to go anywhere with your lives [sic[.”

A Palin family source told TMZ that Willow does not usually use homophobic language and was defending her mother.
