Somewhat surprising/hypocritical that R. Miller would state directly a policy opinion (or existential qualifier on a controversial issue) regarding the state of Israel or what it should do since his hashqafa was to have nothing to do with the "evil atheist zionist state." With all due respect to a great man. This also reflects the difference between a rabbi who is live, on the ground, practical and relevant vs. someone who is "out of touch" with the realities by sitting comfortably in galuth. The opinion can't possibly be well-informed, nor particularly astute. I think we see that here. And I think that basic truth is unavoidable.
Some "Ethiopian Jews" (ie blacks that came to Israel calling themselves such) are really Jews, and many of them did a conversion to solidify it in case of doubt. How can anyone question such a group? They serve in the army, they get educations, they try to be good citizens, and they identify with Jewish culture and practices (even despite discrimination that they unfortunately face). There are such Ethiopian Jews in Israel. R. Miller makes a mistake when he labels all of them as one and the same. As if all the missionaries who snuck in, and at the same time all the sincere real ethiopian Jews are just one big conglomerate of "ethiopian Jews" who are "not really Jews." Of course, if one pointed this out to him, he would correct himself and of course he did not mean that. But because mifletzet hates black people, he would like to present as if R. Miller does too, and as if this cherry picked quote supports his view that all ethiopian Jews should be carted off to ghettos, thrown out or not allowed in Israel in the first place because their "just blacks."
Many of the REAL ethiopian Jews who are sincere, despise the phony missionary ethiopians who want to sneak into Israel by pretending to be Jewish and doing a phony conversion if necessary. Because this group of people (the missionaries) made life hell for the real Jews back in Ethiopia, for many years.
Mifletzet would lump in the real black Jews with those fakers/Ethiopian non-Jews they rightfully hate.
