There's a huge affection with the Spartans in popular Western culture, and it's an old thing actually. This admiration and affection is utterly unwarranted.
|(yes, I know where this is from)|
Let's look at a short description of their society:
The citizens lived mostly in their city, had subjugated several more numerous people, weren't productive themselves but focused on the profession of arms, had their subjects do the work (mostly agricultural work) for them, women were at home doing the homework and rumour has it that the weak or crippled children were effectively euthanised.
Does this remind you of something? Well, it should. For everyone who thinks that this is in any way desirable will would either do so with Hitler's idea of Germans dominating Eastern Europe as 'Lebensraum' or be a hypocrite.
The so-called "Spartans" (Lacedemonians) were essentially protonazis, lacking only the Führerkult; absolutist tyranny. They sure made up for it by having outright slaves (as did the other supposedly civilised ancient Greeks, of course).
Frankly, I'm tired of this.
Whenever "Spartans" appear in fiction, you should side with their opponents, not with the protonazis.
