As I understand it, our mesorah only offers muted criticism of the fools who converted the Cuthim.
A Beit Din who converts insincere converts should pay a price.
I hope the foolish Jews who declared Jewish the Cushim from Ethiopia, and brought them to Israel will be held accountable for importing a people who will be a curse to the Jewish nation for generations to come.
The king of Assyria therefore decided to send some Kohanim of Israel to teach the Cuthites how to keep the Torah. The Cuthites, because of the plagues, decided to accept some of the Torah. They began to worship Hashem, but it was soon discovered that they had not stopped worshiping their idols. They were doing some odd combination of both. Nevertheless, the lions went away. (You can read about all this in II Kings, Chapter 17.)
Since the Samaritans still worshiped their idols, their conversion was not proper, and it was unacceptable. The Jews could therefore not accept the Samaritans as Jews. For this, the Samaritans developed a deep and terrible hatred for the Jews. They did whatever they could to destroy the Jews. They would send messages to the enemy overlord, claiming that the Jews were planning to revolt. They tried many times to get the Jews killed.
They also built their own temple on Mount Gerizim, and there they worshiped an odd combination of religions, which includes their distorted version of the Chumash, and idolatry. Their temple was dedicated to both G-d and to their own pagan idols.
I hope the Jewish tradition primarily holds the Jews responsible for getting tricked rather than the desperate Cuthites who were only pursuing their group interest of not getting eaten by lions.
I hope America’s leaders are held responsible for allowing in over the past 50 years millions of people who are not a good fit with America.
