Whilst i dont generally believe in the concept of cultural appropriation surely denying the People of the Eastern Empire the right to define THEMSELVES must come pretty close to being a perfect example. It does not matter really what anyone else thought, but them frankly...Which is a great failing of people such as these imo. They forget to recognize that there is no fundamental difference between the Pope and Emperor, it is not as if the Pope exists as a spirit aside from this world. Regardless, such people are devotees of Justinian I, they bathe in the ideals of Imperial 'deification' as stipulated by the Second Council Constantinople and are inundated with a Heraclian understanding of the Church as simply devices of Imperial commanding. Something that breaches the past Roman customs regarding the relation of the Papacy and Church to the state not to mention, legal rights that the Papacy had over the Emperor prior to the Second Council of Constance (such as appointment and powers to revoke titles that the Emperor held).
