The Jews of the Babylonian Exile would have been very familiar with what is now called 'idolatory' since this was practised in Jerusalem before the Exile. Ezekiel 8:10 graphically describes some the images that had been in the Jerusalem Temple before its destruction. Monotheism had not yet entirely replaced the old ways.
The kings of Judah had even kept horses dedicated to the sun and there were chariots for the sun until they were removed from the Temple by King Josiah as inimical to monotheism (2 Kings 23:11).
Overall, the Jews would not have been surprised or challenged by the Babylonian culture.
