How many of them are you saying are not "in Communion", or do not adhere to a common creed(s), with each other?
I am Lutheran-Missouri Synod and can state for a fact that we are in communion with many of the Lutheran “branches” you mentioned above. You have to remember that just because a body of Lutherans in a particular country or region gives itself a name, does not mean it’s defined by a separate theology or doctrine. Some groups are definitely far-out liberal or marginally Christian, denying even the fundamentals that mainline Catholics and Orthodox all adhere to. But that is the exception. By and large, we all consider each other brothers in Christ.
