A radical blogger who claims the MTA is refusing to run her subway ads likening the enemies of the Jewish state to “savages” has given the transit agency an ultimatum.

Pamela Geller’s lawyer sent a letter to the MTA today demanding approval of her controversial ad by Friday.

If the MTA doesn’t respond by then, Geller said she will take them to court for violating her First Amendment Rights.

“This is fair warning,” Geller writes in the letter.

She applied to place her ads in the subway last week, but still hasn’t heard from the MTA.

Her strongly-worded ad reads, “In any war between the civilized man and the savage, support the civilized man. Support Israel. Defeat Jihad.”

Geller — co-founder of the American Freedom Defense Initiative — wants to run her ads to run as a rebuttal to billboards from an anti-Israel group.

The Westchester County based WESPAC Foundation has placed ads in over a dozen stations.

Those ads features pictures of smiling children with the message, “We are on the side of peace and justice. End US military aid to Israel.”
