If one civilization is taking revenge on another I don’t think they would show that much nuance.
For one thing, wouldn’t everyone claim they were against their old polis? How would the invaders have any idea who was an idiote?
I just don’t believe it’s at all easy to avoid the fate of your nation , and I especially doubt that the politically ignorant have a better chance of avoiding that fate than the well informed.
I did say higher chance, not guaranteed to avoid it.
The counter extermination was only 5% of Athens total population, or so historians say, so it seems like a lot of nuance was shown.
