Dunno if they should have an ethno-religion. Talman religion is a lot like Judaism, complete with a Talmud (the Imthumăytil)
Maybe the Swuntsim do have an ethnoreligion but don't have a Talmud
Traditional Swuntsim belief holds that all Swuntsim are descended from Ücəgüsvaσ (Sacred Swuntsim: ʔUkwəwusmaσ).
Polygamy is banned, unlike in Talman culture.
Modernist Swuntsimism (Swuntsim: pdaSfətsiv tibayəξoeσ) is a modern Talman liberal form of Swuntsimism which developed after the Groudian Revolution.
