From Towleroad (emphasis mine):
Voila, the "manifesto" of the Paris suicide bombers, in their own words.
Their obsession with sexual revenge, the revenge of the sexually rejected, is intense: They referred to the Bataclan nightclub as a place where where hundreds of "apostates" had gathered in a "profligate prostitution party"—that means a rock concert.
Bohemian Paris is on top of ISIS' target list because it is the country of "obscenity and perversity." Again, it's Paris' mythic reputation for the libertine, for free sexual exchange, for romance and unashamed ecstasy.
This "faith army," this death cult built on sexual repression masked as religious purity—has a detailed manual about how to run a sex-slave market of their war captives, including rules of inheritance. Essentially, you can't be a soldier in their army unless you buy into the faith that beautiful women everywhere are taunting and rejecting you, but you will teach them all a lesson by enslaving and raping them all day long—same with young boys. Everything "depraved" is holy when you're inflicting it upon a slave—makes perfect sense, right?
At some point your Grand Wizard arranges a marriage with an appointed virgin your parents picked out for her dowry. She is of no erotic interest; she is a nonperson except as your baby-receptacle and income source. Siring sons is her husbandry.
Meanwhile, you monitor all the women's menstrual cycles and the puberty of the young boys and girls in your slave pen so you can be sure to rape the right person on the most advantageous day, repeatedly shouting God's name when you come.
VOMIT. Vomit. Vomit.
Every fundamentalist religion today is running on the fumes of sexual psychosis. They are huffing and huffing and huffing until they annihilate everything including themselves.
