"i see state actors as concrete individuals acting on behalf of that abstraction"
Does the individual have to intentionally act on behalf of the state to be a state or actor, or does unintentional action also count?
in my view, an individual acting on behalf of the state is a state actor in that behavior, regardless of their intent. however, context is everything. i see a huge difference between someone who inadvertently acts in a way that benefits state power, and one who consciously chooses to support/impose state power as a matter of course, eg cops, politicians, military, snitches, etc.
does that sufficiently answer your question?
