Sparta was violent totalitarian regime. To use modern example, German nazi had not done circumcision either, but did sterilized or killed the disabled.

> rom what i recall spartans were also composed from largely slaves,gladiators,foreign people, and usually those people are not keen towards tyranny

Slaves are living in tyranny by definition. There is no slavery if there is no tyrant. The majority of Sparta were slaves, the minority was keeping them slaves via violence. The decisions were made by slaveholders.

Sparta was not a place where escaped slaves would seek refuge nor a place where they would made decisions.
