Journalism Kuntzman previously worked for the
New York Post, writing the column "MetroGnome," which ran during 1995–2004. He had a weekly column for
Newsweek online that ran during 2001–2005. In 2005, Kuntzman became editor of
The Brooklyn Paper, a group of community newspapers covering
Kings County, New York. During his tenure, he won awards for Editor of the Year and Columnist of the Year from the Suburban Newspapers of America. His editorial writing also won awards from the Independent Free Papers of America. That organization also gave The Brooklyn Paper its Vic Jose Award in 2009. In 2012, Kuntzman became deputy managing editor for news at the
New York Daily News, Kuntzman faced widespread ridicule for the article, particularly the claim that he suffered from PTSD, with some critics saying such a claim diminished the severity of PTSD suffered by veterans. Kuntzman later wrote another article further criticizing gun owners, noting that many of them had sent him videos of "7-, 10- and 12-year old girls" firing the weapon while smiling. In April 2016, Kuntzman criticized U.S. government's
drone assassination program and implied that the
Obama administration may be guilty of
war crimes. He also wanted President Obama to apologize for the
atomic bombings of Hiroshima and Nagasaki in 1945. The Russian Foreign Ministry spokeswoman wrote on her Facebook page to Kuntzman: "you have said that the fight of the Jewish people against anti-Semitism in 1930s amounts to the terrorist ways of the
Islamic State and
Jabhat al-Nusra ... Are they really the same to you?" In 2017, he began work as breaking news editor of
Newsweek; he was fired in February 2018. He joined
Streetsblog NYC as its editor-in-chief later that year in July.
Activism Kuntzman was featured in a December 2022
New York Times article that focused on citizens "cleaning up" license plates which had been intentionally damaged or obscured for the purpose of avoiding tolls and speed cameras. A subsequent article in
The New Yorker and a segment on
This American Life featured the same work. Kuntzman described himself as a supporter of the
Democratic presidential candidate
Hillary Clinton. ==Personal life==
