James Bennet, the Op-Ed Editor who had hired both Weiss and Stephens is Jewish. His brother is Colorado Senator Bennet. Their mother was in the Warsaw Ghetto and was sent out as a child by her parents just before the Nazis shipped the entire ghetto to the camps. She has an on-line oral history in the holocaust museum.
Both Stephens and Weiss are not only Jewish, but pro-Israel. Weiss had even written an entire recent book about anti-Semitism [1]. Many in the far left support the anti-Semitic Boycott Divest Sanction (BDS) movement against the only Jewish country in the world. China invaded Tibet, puts 3 million Muslims in camps, taking their DNA and facial recognition but no China BDS.
Bennet had also been Jerusalem Bureau Chief for NYT for 3 years and thus would be knowledgeable about the situation there. He may have stopped inaccuracies printed about Israel in his role.
Bennet was the likely candidate to be elevated to Exec Editor when the current one retired in a couple of years. I believe a lot of the staff didn't like Bennet because of Jewish/Israel stance and the idea of him being the Exec Editor frightened/angered them.
I believe that an external inspector general type figure should evaluate the entire situation. Weiss's complaints are consistent with a toxic work environment that nobody should have to deal with. She said the source of some of the harassment she experienced was on an internal slack channel and thus easy to investigate.
Readers of HN are analytical enough to realize that when something obvious isn't mentioned it may well be the underlying cause.
