It’s clearly a parody.
Take, for example, the claim that the Romans NEVER interfered with the local religions, and any and all gods were allowed in the colonies. This breathtakingly wrong opinion completely ignores the local and empire wide persecution of Christians over a few centuries, not to mention Pilate, as Roman governor of Jerusalem, sentencing Christ to death.
Take, for example, the claim that there was little rebellion. What utter nonsense. How about the three Jewish revolts, including the Great Revolt; Boadicea revolting against the Romans in Britain; the German Hermann Cherusci who defeated the Romans at the Battle of Teutorburgerwald; Vercingetorix’s revolt in Gaul, and countless other revolts across the Roman Empire. Hasn’t the author ever heard of Spartacus?
Of course, the other possibility is that’s it’s not an intentional paradoy but it’s been written by an ignoramus who has no idea what he’s talking about, in which case it’s even funnier. And the arguments it makes are even more absurd.
