People get most of their info about Sparta from that stupid comic. Athens was a slave state as well, but was basically the foundation of Western culture. All we got from Sparta are a couple of cocky one liners.
I mean I hate basically every aspect of Ancient Sparta. There is nothing I loathe more than slavers. Basically fuck most of Ancient Greece. But I hate the Spartans the most because I find their system loathsome.
The AK is an interesting choice of rifle for that one, the SKS might have a touch more irony but still, being a little right wing trumpet sporting what used to be the symbol of the second world....
These types dont know anything about guns, they may be able to shoot them but the background, development, and history of the weapon is of not relevancy to them. If I was to fix this graphic id swap the AKs with either a pair of Colt M16s or FNFAL, ya know the left and right arm of the free world. Also id center the damned image something this profligate was apparently incapable of doing.
