Don't think so? Listen to what she says at around minute 28.00.
Once you listen, then kindly explain to me what else Warren meant when she said,
"...you couldn’t keep pushing harder because over time realities are bearing down on Israel, demographic realities, births and deaths."
The "demographic realities, births and deaths" she refers to are Palestinian children.
It is clear that she is spouting the AIPAC party line concerns about "Israeli demographics", i.e. Israel belongs to the Jews (including all of the settlement land they can steal) .
Any Palestinian who was driven out of the country (and who are denied the right to return nor any compensation for their stolen land & property) have no recourse whatsoever and the Palestinians who stayed are treated as second-class citizens.
Israel's problem, as expounded upon by Warren, is that these second-class citizens dare to have non-Jewish children and that "endangers" Israel's apartheid loving Jewish majority.
Now imagine if Ms. Warren were to dare say that Blacks or Hispanic having "too many babies" was a legitimate concern for the white ruling class in America?
Any politician who dared to say that would be branded a racist and would rightly so never have a chance at gaining a political office.
That she said it about people who reside in another country should make no difference.
Racism is racism whether it is supported in the United States of America or whether it is supported in Israel.
By her own words, Elizabeth Warren is a racist.
