The fact is that it isn’t a rule, it’s saying. Much like the song lyric, “War, what is it good for? Absolutely nothing”
Well actually, war freed slaves in the US, freed Europe from the NAZI’S.
The fact that you are seeing it played out, in your own era, and you are denying it, makes this whole exchange kinda hilarious and a waste of my time. And that song lyric was an opinion.
