Yes. It seems there is a 'pre-shunning' mentality to irregular, inactive ones. Soft shun, cold shoulder.
I don't see how the Borg can do away with blood transfusion policy, shunning and two - witness rule without the Borg collapsing in on itself. Those 3 things alone are the most damaging. Seems if the Borg does away with any one of those, the Borg collapses.
