You have not shown that your usage is entirely standard - myself and others have repeatedly pointed to aspects of Wikipedia articles that contradict your use of the term. "Office politics" is not casual language, it actually is using the term "politics" as most refer to it in modern times: the process of determining power arrangements among beings. But this is still semantics. I can accept your definition of politics as being the activities within the state. Lets call "the process of determining power arrangements among beings" as "power struggles". I've claimed there are a number of thinkers that have varying views on "power struggles", some of which presume a state, others of which do not. One thing that seems to be clear is that there will always be power struggles in any community of beings: no system will eliminate them. So the question is, on what basis do we agree to contain power?
