From a New York Times story by Anemona Hartocollis headlined “How Harvard Students Became the Center of a Free Speech Fight”:

On a campus already bitterly divided, the statement poured acid all over Harvard Yard.

A coalition of more than 30 student groups posted an open letter on the night of the Hamas attack, saying that Israel was “entirely responsible” for the violence that ended up leaving more than 1,400 dead, most of them civilians.

The letter, posted on social media before the extent of the killings was known, did not include the names of individual students.
