Question: What did the literate segment of Greeks consider to be a part of their ethic lines ?
Sentence: For those that remained under the Ottoman Empire's millet system, religion was the defining characteristic of national groups (milletler), so the exonym "Greeks" (Rumlar from the name Rhomaioi) was applied by the Ottomans to all members of the Orthodox Church, regardless of their language or ethnic origin.
Answer in sentence: no
