While the Jews never forcibly imposed Judaism, Christians and Muslims drew the logical conclusion and forcibly imposed Christianity and Islam. However, it is also not clear that Judaism was the only pre-Christian monotheistic religion. There are monotheistic elements in some sects of Hinduism, Zoroastrianism, and Yazdism.
the Jews rejected the gods of everyone else.
I would point out that the statement “Jews never forcibly imposed Judaism on non Jews” is false.
Around 100 BC the Jewish king of judea, john hyracanus, invaded Edom and forcibly converted them to Judaism.
One of those forcibly converted was Herod the great’s father.
Incidentally the Idumeans ie Edomites, ended as a people in 70 AD when they died defending Jerusalem against the Romans
Hinduism at best is Henotheism, with the concept of Ishwara as being the primeval God from whom the others emanate. But that belief dates from after Christianity reached India in 52 AD.
Zoroastrianism until Zurvanism, the sect promoted by the Sassanid empire starting from 224 AD, was sternly dualistic with Ahura Mazda, the god of light, being equal to Aingra Mainyu, the God of the lie.
As for Yazdiism, I believe it post dates the arrival of Jews in Babylon
“Jews never forcibly imposed Judaism on non-Jews.” Of course not. Gentiles were despised. Christ himself ordered his disciples to have nothing to do with them, and he himself only had relations on, as I recall, three occasions before appearing before Pontius Pilate and meeting his death. Before Paul came along, and the world was changed through the intercession of the heavenly Christ himself, gentiles and jewry were an anathema.
