(JTA) — Anti-Islam activist Pamela Geller was banned from entering Britain. 

Geller on Wednesday posted a copy of a letter from Home Secretary Theresa May dated June 25 on her anti-Islam blog Atlas Shrugs that informs her that she is barred from entering the country.

The letter states that her “presence here would not be conducive to the public good.” It adds that the home secretary is concerned that Geller might engage in behavior that would “foster hatred which might lead to inter-community violence in the UK.”

Geller and Robert Spencer, co-founders of the group Stop Islamization of America, had been scheduled to participate in a London rally organized by the far-right English Defense League. Saturday’s rally will be held at the site where a British soldier was killed by two Islamicists using a meat cleaver and an axe. Spencer also was banned from entering Britain.

“In not allowing us into the country solely because of our true and accurate statements about Islam, the British government is behaving like a de facto Islamic state,” Geller wrote on her blog. “The nation that gave the world the Magna Carta is dead.”

More than 2,000 signers of an online petition are calling on May and British Prime Minister David Cameron to reconsider the decision, which is binding for three to five years.
