I couldn't tell you. YPG was dominantly left-wing and looked up to the former communist 'Apo'. I imagine the phenomenon is fairly politically universal.

>There is genuinely a group of people who'd rather fantasize about mass murder than do chores. Every now and again one of them actually picks up a gun. Then some school kids never have to go to events, or anywhere, ever again.

Yes there are people like that. Although most of the Kurds I met started fantasizing about fighting ISIS only after Islamic theocrats starting murdering and raping their population. I doubt many of them who gained a taste for combat were doing chores one day and started fantasizing they could live under a tyrannical regime so they'd have an "excuse" to "restart" the war.

Personally I don't think soldiers in need of a war have to fantasize too hard to come up with a morally acceptable outlet. I wouldn't look down on those who fought against the Russians in Ukraine or against ISIS in Mali because they need an outlet for their escape from civil life.
