I think you radically misunderstand the distribution of viewpoints of your fellow Americans (on Biden, on "genocide," and on selling our weapons to our military allies).
I’m not sure why you’re pointing specifically to American Jews as the source of authority on a conflict in the Middle East, but in terms of polls and surveys:
“About a quarter [of Americans] (27%) say Israel is going too far in its current military operation, while about as many (25%) say it is taking the right approach; 16% of Americans say Israel is not going far enough militarily.” So more Americans support Israel’s campaign than do not.[1]
“81% of American Jews support Israel continuing its military operation to ‘recover all Israeli hostages and remove Hamas from power.’” Which implies the vast majority of “prominent American Jews” are not calling this genocide.[2]
And on this last point, this is hardly a “textbook example of genocide” when scholars of genocide contest this label[3], it is outright rejected by the US State Department[4], and casualties fall within the expectations of urban warfare experts[5]. The textbook example of genocide is the Holocaust.
All this hyperbole and generalization, just like we saw in Paul Graham’s tweet, makes it impossible to have productive discussions.
> I’m not sure why you’re pointing specifically to American Jews
They weren't. They were referring to prominent American Jews. They probably have specific statements in mind, by specific individuals but for the sake of brevity, didn't include them.
> For all those asking why there is no education Gaza. Oops, we've had a missile fall on them. That sucks. Ohhh, too bad. That's how you'll not be engineers anymore.
And then there's the murder and attacks on civilian infrastructure in the West Bank, too. Or the bulldozing of a cemetary. I'll spare you posting dozens and dozens of pieces of proof each of which belie the claim of calling this a "war", much hiding the arbitrary, cruel attacks on civilians under the cover of "urban warfare".
As for "productive" discussions, for the purposes of ethnic cleansing and genocide, all that is required is a.) to continue sending arms b.) pretending this is a defensive "war".
