You're using a rather glossed over small to dismiss the large.

You are right - it's somebody with some food sharing one time. That's what it is, in the small.

But in the large, what do you call it? You want to describe a society where such acts are common place, and perhaps compare it to a society in which it is not. Or you want to discuss the relative frequency of these acts. At this point, you need more than "just a little thing a person did once that doesn't mean anything" to work with these concepts.

Then you get politics thrown into the mix, propaganda every which way, and next thing you know you've got somebody complaining about others "clinging to Marxism" on the internet.
