NEW YORK -- The questions on the ads aren't subtle: Leaving Islam? Fatwa on your head? Is your family threatening you?

A conservative activist and the organizations she leads have paid several thousand dollars for the ads to run on at least 30 city buses for a month. The ads point to a website called RefugefromIslam.com, which offers information to those wishing to leave Islam, but some Muslims are calling the ads a smoke screen for an anti-Muslim agenda.

Pamela Geller, who leads an organization called Stop Islamization of America, said the ads were meant to help provide resources for Muslims who are fearful of leaving the faith.

"It's not offensive to Muslims, it's religious freedom," she said. "It's not targeted at practicing Muslims. It doesn't say 'leave,' it says 'leaving' with a question mark."

Geller said the ad buy cost about $8,000, contributed by the readers of her blog, Atlas Shrugs, and other websites. Similar ads have run on buses in Miami, and she said ad buys were planned for other cities.

Metropolitan Transportation Authority officials said Geller's ad was reviewed and did not violate the agency's guidelines.

"The religion in question would not change the determination that the language in the ad does not violate guidelines," MTA spokesman Kevin Ortiz said Wednesday.

All ads are screened, MTA spokesman Aaron Donovan said. Most are reviewed by the company that handles the MTA's advertising opportunities, but some are sent to the MTA for ultimate approval.

The agency had received no complaints since the ads went up on May 14, MTA spokesman Aaron Donovan said. The 30 or so buses with the ads pass through all five boroughs of the city.

Faiza Ali, of the New York chapter of the Council on American-Islamic Relations, said the ads were based on a false premise that people face coercion to remain with Islam. She said Muslims believe faith that is forced is not true belief.

"Geller is free to say what she likes just as concerned community members are free to criticize her motives," Ali said.

Geller has a history of speaking out against Muslims, and the ads are "a smoke screen to advance her long-standing history of anti-Muslim bigotry," Ali said.

Geller said she had no problem with Muslims, but was working to "maintain the separation of mosque and state." She is also among those speaking out against the building of a mosque and cultural center near ground zero.
