The fiscal control board that oversees the Massachusetts Bay Transportation Authority voted Monday to ban a vast swath of controversial ads, minutes after hearing from dozens of Israel supporters furious over an ad they called “slander,” “incitement,” and “poisonour hate speech against Jews.’’

The ad at the Davis Square Red Line station, paid for by the Palestine Advocacy Project, asserts that with U.S. financial support, Israeli forces kill a Palestinian child every 3 days on average.

During a heated and rowdy public hearing, several backers of Israel called it a deliberately dishonest mischaracterization of collateral civilian deaths they said Hamas and other Palestinian groups deliberately provoke to generate negative publicity against Israel.

In today’s context of terrorist attacks including recurring stabbings of Jews in Israel by Palestinians and other attacks, Charles Jacobs of Americans for Peace and Tolerance said the ads could incite violence against Jews and told the T board: “You're putting the Jewish community here in danger.’’

The T board, which already had a new policy on what ads to accept and reject on its agenda, later voted to adopt, starting Dec. 1, a total ban on advertising “concerning political issues or matters of public debate … about economic, political, moral, religious, or social issues.’’ The policy also extends bans on alcohol, tobacco, firearm, pornography, and adult entertainment advertising, and bans advertising portraying dead or injured people, fetuses, or animals.

Sarah Wunsch of the American Civil Liberties Union of Massachusetts spoke out against the policy, saying: “That’s going in the wrong direction for a free society. This is public space.’’

Richard Colbath-Hess, a board member of the Palestine Advocacy Project, said: “The ads are 100 percent factual … The Israeli government uses U.S. money to bomb and shoot Palestinian children. It's just a fact.’’ Colbath-Hess, who described himself as a Jew and son of a Holocaust survivor, said criticizing the government of Israel is a valid exercise of free speech and does not equate to anti-Semitism.

“The solution to free speech is more free speech,’’ Colbath-Hess said. “If you don't like what's on the T, look away, or put up your own ads.’’

But Jacobs said of the murdered-children claim in the controversial ad: “They're killed because they're being used as human shields. The Palestinians put their women and children in front of them when they're firing rockets.’’ Jacobs said his group tried to take out rival ads, including one denouncing jihadist terrorists as “savages,’’ but the MBTA refused to put them up. Jacobs and several of his supporters are demanding Governor Charlie Baker find out who at the T approved the Palestine Advocacy Project ad and refused their ad, and get that person or people fired.
