You yourself said it best: "If it's not jurisdictional, then it is theological, but if you eliminate both, then it is the laity, the liturgy, dispensations, anything is cited as the reason(s) why reunification is not a good option".
Orthodoxy is not just doctrinal, Alex. It's the way of life, a culture. Ignoring the doctrinal, an Orthodox will look at the Wiccan nuns or the NO liturgy and say "That's not Orthodox. That's unrecognizable!" and walk away. They will do the same thing if they happen to be in an Anglican church or a at a Lutheran service. They will find very little or nothing in common with them. That's not lack of love. It's just lack of Orthodoxy.
