I want to know the answer to the following question:
What other cultures do the Romioi  clam to be their birthright ?
All the background I'm provided with is that "Byzantine Greeks called themselves Romioi and considered themselves the political heirs of Rome, but at least by the 12th century a growing number of those educated, deemed themselves the heirs of ancient Greece as well, although for most of the Greek speakers, "Hellene" still meant pagan.". Is that enough to answer the question?
Answer: yes
