>papal supremacy and infallibility
The Orthodox claim to believe that the bishop of Rome is the first among equals, but since schisming this means nothing. It's always been understood that the Rome would settle disputes and councils, and that the pope of Rome and successor of Peter had the last say. The Orthodox have no way of holding any more councils, there is no first among equals for them because of there separation from the larger church. The Eastern Catholics are closer to the early church than the Orthodox, and are more honest about their theology
>Filioque
This isn't an important issue, nobody knows the exact metaphysical workings of God, what we do know is what he's commanded of the church to spread the gospel to all nations and the moral law. Unity is more important than who's right about esoteric theological speculations
>Divine Simplicity
I'm not an expert on this but I have a feeling it's no different than other issues that Orthodox claim as reasons for separating from Rome
>Original Sin
The effects on the fall are the same in the west and east, in my eyes this distinction is not as big as it's made out to be by schismatics
>Immaculate Conception of Mary
Eastern Christians have always believed this but never had it authoritatively defined, this is a similar theme throughout most of these differences and excuses to separate from Western Christians
>Created Grace
Again esoteric theological speculations on the nature of God's metaphysical workings are not important, there's room to discuss these things within the universal church, I have a feeling the Eastern view on these things are a result of differences in language and culture
>Purgatory
Eastern Christians absolutely believe in purgatory, they don't describe it in the same way as the west, have you ever heard of Toll houses? Eastern Christians believe that the souls of those who love God will be purified by God's light, this is what Catholics believe about purgatory. It's the same concept, not a reason for schism
>Forcing Priestly Celibacy
Priestly celibacy is superior and a discipline not a theological or moral truth, however Rome allows the Eastern Rites to have married priests.
>Dogmatism
This is a meaningless term, the church has always believed in objective truth and revelation, I think a lot of people become Orthodox because they believe that it's somehow more relativistic than the RCC and that makes them feel better. Read the early church fathers, they were all very dogmatic just as Jesus Christ is.
