Greek Orthodox 98%, Muslim 1.3%, other 0.7%
I hardly think the Pope or any other (non-Orthodox) leader would have much influence on Greek state policy. But it's hardly a case, I think, of Hindus being singled out. They've had little to no contact with ANY non-monotheistic religious group: Buddhists, Shintoists, Buddhists, Sikhs, Santeria, Makumba, Rastafarianism, or anybody else.
They (Greeks) have had no historic conflicts with Hindus or India as far as I know; so the Hindu question may never have come up. I don't suppose there has ever been any Indian influx into Greece. Do you know?

Dont have much time. For now I would only say that you are switching cause for effect. The insignificant numbers from other faiths is because those religions aren't given the breathing space. Its the same in Italy and a few other Christian countries.
