They also position things in such a way that implies antisemitic things, such as saying that Zionism is only 200 years old, or discussing the Israel wars only or primarily through an Arab lens.
These biases around Jewish topics are small individually but large in aggregate, especially in how they present Jews and Jewish topics.
Multiple Jewish and civil rights organizations have done a more comprehensive job at discussing this, even organizations who don't usually agree on things. While they talk about "anti-Israel bias" Wikipedia articles on or mentioning Zionism (80% of Jews are Zionist) are IMHO just as, if not more damaging, and demonstrate the issue.
Most importantly though, talk to the Jews in your life about this. They will tell you.
