"Antisemitism is on the rise globally," he stated. "Jews make up only 2.4% of the population of the United States but are the victims of more than 60% of all religious hate crimes, according to the FBI annual report.
"Whether or not Kanye West is mentally ill, there's no question he is a bigot," he continues. "His hate speech calls for violence against Jews. If you interpret his words any other way and defend him, guess what? You are a racist.
"If we don't call someone as influential as Kanye out for his divisive, ignorant and antisemitic words, then we are complicit. Silence is complicity."
Other celebrities who called out Kanye West
A few other Hollywood celebrities were among those who called out Kanye West. Actress Jamie Lee Curtis, recently tweeted, "The holiest day in Judaism was last week. Words Matter. A threat to Jewish people ended once in genocide. Your words hurt and incite violence. You are a father. Please stop."
Actress and comedian Sarah Silverman also released a statement on her Twitter. "Kanye threatened the Jews yesterday on Twitter and it's not even trending. Why do mostly only Jews speak up against Jewish hate? The silence is so loud," she wrote.
Josh Gad, Michael Rapport and others have posted to their Twitter accounts as well.
