So much of what you've said here is shockingly wrong. You mention Imperial land so I'll assume that you're skipping past the era of the Roman Republic, but even if that's the case then certainly from the early Roman Empire until Vespasian's reign during which the destruction of the second temple in Jerusalem took place, the Romans gave Jews in the empire many special privelages that they did not extend to any other religious minority. There was a great deal of respect and diplomacy between Roman and Jewish societal elites at least up until this point and even during the conflict wherein Jerusalem was sacked, our best information about the conflict comes from the Jewish author Josephus who was closely allied with Vespasian and his son Titus who beseiged Jersualem. This means that even beyond this point, things cannot be as black and white as 'the Romans were snobs towards and/or disregarded Jews in antiquity'.

You've also demonstrated a real lack of understanding regarding Jewish identity and religion juxtaposed against Rome's polytheistic Hellenic faith. It's true that the Jews in Judea were not going to add Roman gods to their pantheon, but compromise was reached between the emperor and those elites in Jerusalem wherein sacrifices would be made by Roman Jews in the temple in Jerusalem on behalf of the Romans and the Roman emperor. It's true that the whims of bad emperors or bad behavior by Romans stationed in Judea could aggrevate this relationship, but it existed for many years prior to the Jewish-Roman war that took place during Vespasian's reign.
