I have yet to meet a person in reality who ever sincerely apologizes when a club is held over their head, but I won't argue that point.
Your argument may work for Sabcat, but it doesn't work for Optimistic. *He* never claimed to be government...he was a new member. See, he isn't a prominent member of government and yet IRON directed its ire at LSF to pay reps for his actions. Hal's actions were a deliberate action to instigate a particular FA path on an alliance, and Optimistic did the same. Both were excused away by their respective "governments", but one has to have their collective pay the price.
Hell, stupid raiders cause this issue all the time, and yet we somehow avoid going to war over it.
By that argument, I would expect Valhalla to have a tighter rein on members posting inflammatory material than I would a group of anarchists. You know, if we are using logic here.
