Most people don't approve of occupation, genocide nor ethnic cleansing and that was taking place in Gaza on a daily basis for all the world to see, and of course it still is.
The protests were a mass national and world wide movement involving hundreds of thousands if not millions of people against those inhumane atrocities and what did much of the media do, label the protesters as being anti-Semitic with no regard to what was happening to the Palestinian People, most of whom never voted for Hamas; which was enabled to power by Netanyahu.
It was so bad that President Biden stopped sending 2000 lb bombs because entire neighborhoods were being destroyed.
So it was obvious that Netanyahu was in bed with Kushner and *rump, that he didn't care about the political damage he was doing to President Biden nor the Democratic Party any more than he cared about the Palestinian People because he was primarily focused on avoiding corruption charges, so his motives were highly suspect and yet the arms kept flowing.
Most of the people protesting were younger, idealistic and in universities, they were Biden's natural base and they were being trashed as anti-Semitic, wrote off or ignored.
So whoever was advising President Biden on Israel's policies against the Palestinians did him and the Democratic Party no favors.
