While even so called Kahanist yishuv of Tapuach has Arab workers,Bat Ayin has a strict rule of Jewish labor only.
Also it is against the rules to own German cars there
Furthermore Arabs know better than to wander into Bat Ayin because their safety can not be guaranteed.
So why do so many Kahanists live in Tapuach rather than Bat Ayin?
Bat Ayin makes more sense.
