I disagree, I am a slave to sleeping and eating and defecating, doesn't mean "I might as well be a slave to vicious brown people as well, what's the difference?".Frankly, the mix of Spartans and FREEDOM is kinda... funny. Sure, they're kinda free. But more like slaves to their city. Impressed into service at birth. In service until the day they're brought home on their shields.
JUSTICE would have been a much better ideal for Spartans to fight for.
If I was fighting off a persian horde I'd feel ok with saying I'm fighting for my freedom, even if technically I can never be free, not being ruled and dominated by a rival strain of hominid is close enough.
Justice? What the fuck would that mean?
