(CNN) -- An anti-jihad ad that has caused a stir in other cities now has another destination for its message: the subways of Washington.
The ad by the American Freedom Defense Initiative states, "In any war between the civilized man and the savage, support the civilized man. Support Israel. Defeat Jihad."
Jihad - Arabic for "struggle" - is considered a religious duty for Muslims, although there are both benign and militant interpretations of what it means.
Last month, the American Freedom Defense Initiative posted the ads in the subways of New York and San Francisco.
The Council on American-Islamic Relations posted a response ad that reads, "Help stop bigotry against our Muslim neighbors." Another one reads, "Support peace in word and deed."
And the council is ready to try to counter the new ads in the nation's capital.
The ads were initially blocked, but on Friday, U.S. District Judge Mary Collyer ruled that the D.C. transit system must allow the advertisements because of free speech rights guaranteed by the First Amendment.
"We don't think it's controversial," said Pamela Geller, the executive director of the American Freedom Defense Initiative. "It's truth. Telling the truth now is equated with 'hate' and 'bigotry' in an attempt to silence and demonize the truth-tellers. That makes my ads all the more important."
According to Geller, the American Freedom Defense Initiative ads have two missions: "to affirm the truth about the barbaric jihad against free people" and to affirm free speech.
The Council on American-Islamic Relations, which is working with the American-Arab Anti-Discrimination Committee and Jewish Voice for Peace, knows it can't get the ads removed. Instead, the groups want the D.C. transit officials to help reduce the negative impact of the posters.
"With respect to your response in this matter, it is not our desire that (the Washington Metropolitan Area Transit Authority) disallow advertisements that contain any political speech," the Council on American-Islamic Relations said in a statement. "I do believe there are measures WMATA can take to mitigate the affect hate speech has on the community."
These measures include working with organizations representing affected Muslim and Arab communities, placing disclaimers to show that the transit authority does not support the views of the ads, and providing free space for advertisements focused on promoting, understanding and tolerance, the Islamic group says.
More than likely, the free ad space will be used for the Council on American-Islamic Relations' ads against the American Freedom Defense Initiative's message.
"The counter-ads are fine from a free speech standpoint," Geller said. "But where were these groups countering 'hate' when the Fogel family was murdered in Israel? Or when the Chabad house was targeted for a bloody jihad attack in Mumbai? Or when Christians are persecuted on an increasingly frequent and violent basis in Egypt, Pakistan, Indonesia and elsewhere?"
Just like the Washington transit authority, the New York Metropolitan Transportation Authority had to display the American Freedom Defense Initiative ads because of a court ruling, despite refusing to allow the ads a year ago.
Although the ads cannot be removed, the executive director of the Council on American-Islamic Relations, Muneer Awad, hopes the MTA will also help reduce the effect of the ads in the city.
"We're trying to make sure MTA has policies to discourage hate speech," Awad said. "These hate ads are part of a larger problem."
The MTA is considering amending its advertising policies to prohibit all noncommercial advertisements, spokesman Aaron Donovan said.
"If they countenance the outlawing of my ads, they should be careful: One day, they may wish to say something that offends the political or media elites, and they'll wish they had stuck up for my freedom of speech," Geller said.
