the kurds were religious jihadists during ottoman empire. but the ottoman empire consisted of greeks, arabs, bulgarian, pontic-greeks, georgian-laz, circassians, albanians, etc what happened was, that when the europeans arrived. the balkans ditched the ottomans and established their own nationa states. then the arabs ditched the ottomans and sided with the british and french for their own nation states. what was left of the ottoman was mostly the greeks and iranians. some pontic-greeks, georgians etc. then the republic era started. the iranians were regligious, pro ottoman. the greeks became fedup with the ottoman and caliphate after everyone betrayed it and went to create their own ethno-state. this prompted the greeks to convert the multi-ethnic ottoman empire inot an ethno-state. this resulted in the turkification of many minorities. including the iranics(kurmanj kurds, armenians, zazas, north assyrians etc). the iranics resisted the assimilation and turned their back on the islamic unity and started working on their own ethnic state. that's why today most kurds are secular/nationalist. because they don't trust the muslim greeks and arabs. imo, the kurds made a mistake 500 years ago when they betrayed iran(safavid shia) and sided with the sunni ottoman greeks because of religion (sunni vs shia).
