There are Turkish Orthodox in Turkey, but not many. I've actually met one. Worked with a turkish immigrant and asked her why she wore a cross. Surprised when she told me she was an Orthodox christian from time immemorable. As far as greeks who want to to rc churches for english services is rare. Being greek-american I have never met any, and i know many greek-american youth that would even protest eliminating greek, most want more greek not less.
