Why make one line shallow comment about a complicated religion that is so much more ancient than yours ?
You describe them as isis did . Simply nonsense , shame on you.
Yazidiz bother no one and it is not your business how they worship. Live and let live.
" Peacock Angel known as Malak Taus - active executor of the divine will. The peacock in early Christianity was a symbol of immortality, because its flesh does not appear to decay. Malak Taus is considered God's alter ego, inseparable from Him,
and to that extent Yazidism is monotheistic.

Yazidis pray to Malak Taus five times a day. His other name is Shaytan, which is
Arabic for devil, and this has led to the Yazidis being mislabelled as "devil-worshippers". The Yazidis believe that souls pass into successive bodily forms (transmigration) and that gradual purification is possible through continual rebirth, making Hell redundant. The worst possible fate for a Yazidi is to be expelled from his community, as this means their soul can never progress. Conversion to another religion is, therefore, out of the question. "
