There was a thread about it on here some months ago, which revealed the man to be very, very confused, accusing us of somehow being Monophysites and Nestorians at the same time!)? Fat chance.
Historically, being called a Monophysite and a Nestorian is a reference to the idea that Miaphysites are:
1. Monophysites that believe that Christ's divinity swallowed his humanity like a drop of vinegar in the sea. Therefore, Christ is not a man.
2. Nestorians that believe that there are two persons one is divine and the other is human. Therefore, Christ is not a man.
So, the Miaphysites are actually being told, "You don't believe that Christ became man."
So in conclusion OO-Miaphysists do accept the council of chalcedon or agree in some what way to it?.
Yes and No...
Most of us OO are willing to unite based on the EO interpretation of Chalcedon that agrees with our faith, not necessarily our interpretation of it., which is not a pleasing interpretation, but nevertheless an interpretation that even EOs will at least agree is not what they believe, faith-wise.
Is not both interpretations of the EO and the OO the same and mean the same thing ?.
When I say interpretation, I mean how one perceives Chalcedon to teach. For instance, OOs will argue Chalcedon was far from Orthodox, in fact, it had heretical elements and it showed instability. EOs will disagree with that interpretation. Nevertheless, more important than interpretation is faith. If the interpretation leads to the same faith, then the interpretation should not matter, should it? If through Chalcedon or the rejection of Chalcedon, we still are Orthodox, then one can interpret it as despite not having literally accepted Chalcedon, by our Orthodox faith, it's as if we accepted it all along. If that is what "accepting Chalcedon" means, then we are more than happy to unite.
At the same time, I'm convinced, it's going to be very difficult to change minds on how to interpret these events. In the end, the Orthodox faith, before persons or councils, matters more, at least from an OO stand point.
