Yezidi/Yazidi: Who Are These People? Inspiration for Halo of the Damned

The news continues to report the Iraq/ISIS situation as they kill, rape, and torture the Yezidi (also spelled Yazidi) Kurds in Iraq. Some of you may even remember Saddam Hussein killing them off in the early '90s during the first Gulf War. The media misrepresented the Yezidis back then as they misrepresent them today, preferring to define the religion as meld of Christianity, Islam, Judaism, and Zoroastrianism.  
I remember Saddam Hussein calling the Yezidis a bunch of devil worshipers as he killed them off decades ago.  The media did not expand on Hussein's comment, but it stayed with me.  In fact, I was intrigued about this obscure religion.  Intrigue turned into inspiration for Halo of the Damned, a horror/paranormal book starring an evil fallen angel who appears to his angel cult.  The cover shows a fallen angel standing in front of a Yezidi congregation.

In my novel as in real life, I am not sympathetic or tolerant of those who worship the devil.  Am I being politically incorrect? 
Disrespectful towards another culture?  

The Yezidis believe there is a God, but He is not who they worship.  Instead, they pray and worship Malak Tawas, the peacock and archangel, known as Satan in the West.  Muslims believe they are devil worshipers which is one of the reasons they want to kill them.  
Yezidis have a book like the Bible, Torah, and Qu'ran.  It's called the Black Book, but it's currently lost. Yezidis go by oral tradition.  Their leader is a secular emir and their society is based on a caste system. Yezidis must marry in their faith.  Like Muslims, honor killings among women are part of the culture.
This religion worships archangels and not all archangels live in Heaven with God.  One third of all angels sided with Satan when he waged war against God.  Am I suggesting they deserve to be targets of murder and rape by ISIS?  No, but...  

Melek/Malak Tawas

U.S. soldiers should NOT be compromised in trying to save them. Let Europe or some one else come to their rescue.
As far as ISIS is concerned, many underground reports claim they were trained by the U.S. in Jordan.  Wouldn't that make them the U.S.'s mercenaries?  Why would the U.S. bomb them after training them?  Did they go rogue-a Dr. Frankenstein situation?  Several reports from all major news channels focus on some of ISIS's monstrosities such as lopping off the heads of men, women, and children, and then throwing them around or kicking them as they celebrate their deaths.  This isn't new.  But when they were doing the same thing a few years back it wasn't publicized.  Why is the news bombarding us with these horrors now?  I'm not sure where I'm going with this, but I believe we are being deceived.  The news is just the abridged/censored version of the true story.  Conspiracies are welcome.  Opinions are welcome.  Leave a comment.
