My thoughts are that I think my meaning is that when you do something, it has effects. It's not what you do that matters, necessarily, but your reason for doing it. If you do something in the name of God (or some other moral cause) (not for God, which I think is a subtle difference), then that will have consequences down the line related to the fact that you did it in the name of God. If you do something out love, there wil be consequences tied to that related to the fact that you did the thing out of love. If you do something out of anger, fear, or delusion - whatever your underlying motive - that will have a specific set of consequences down the line associated with that. You might not be able to guess how they will arise, specifically, but... just that what happens in the future, etc. will be a result of your (and others') underlying motives.
By societal karma, I mean what happens when a lot of poeple have similar underlying motives for doing something and how it affects the society as a whole, such as what laws are made, social norms, etc.
I think everyone could stop fighting so much and listen to each other, but it can be quite hard, and some people might not be ready, so we should just do what we can (and take care of ourselves), I suppose.
