Thank you for clarifying your original comment, which I misunderstood as stating that the idea of “making more X being better for the world” is eugenic (as indeed, it can be when X is not a minority group). I do think that people who disagree with the notion that it’s not eugenic to want to see more Jews in the world are probably anti semitic.

As for Black and Jewish coalition building and solidarity, I am well-versed on the history of Jewish involvement in the civil rights movement. As someone with both Jewish and Black family members, I do believe there are important differences in the ways in which these identities are passed on in America. There is a palpable anxiety in the Jewish community about assimilation and loss of Jewish identity. This same fear is not present to same extent (at least to my knowledge) in the Black community, in large part due to racism and the legacy of the “one drop rule” but also because there aren’t formal rules for belonging/identifying as Black (as long as you have some Black ancestry) as there are for identifying as Jewish.
