I went looking for reports of actual U.S. students calling for genocide. This article says there are none. It also agrees with my previous point that a simple question sometimes can't be answered yes or no. And the article describes the political "dead cat strategy".

The Harvard and UPenn presidents walked into a trap in Congress, December 11, 2023
"She repeatedly asked the presidents essentially the same question: does calling for the genocide of Jews on your campus constitute harassment, yes or no?

The question is a trap, of course, and for several reasons. The first and most important reason is that there’s no evidence anyone since 7 October, or even in recent history, has called for the genocide of Jews on any American campus, public or private. Stefanik’s question implies that such calls are commonplace, but she offered no proof.

The second reason this is a trap is that the question can’t be answered with just “yes” or “no”. Public universities, as state actors, are bound by the first amendment, as are private universities which receive federal funding."

"In politics, a 'dead cat strategy' is used to divert attention away from one issue and on to another by metaphorically throwing a dead cat onto a dining room table in the middle of a dinner party."
