WOW what a thread.
Welcome to the forum Constantine, I must say I am not sure what you are really talking about in your op.
I also live in Athens though I am not a Greek.
Some of the Greeks can be a bit weary at first, they have always been nice and polite to me, in fact most of the time they take advantage to practice their English with me, especially in the supermarkets.
The γριά are always smiling and greeting me in the Orthodox Church that I go to, and some of them are proud to have a foreigner there.
In my church there is an American who is married to a Greek girl, A Girl from South Africa, and myself British.
I agree the Greeks can be a bit impatient with the Americans, but what you have described is a different Athens from where I live, see and experience.
The only trouble I am weary of is Golden Dawn because my wife is from the Philippines, but while we are out together she is very safe.
I really don't like the fact that some of our clergy is blessing Golden Dawn and I find that outrages.
It was a European law that scrapped the need to have your church status on the ID cards, not the state.
Greece is a fantastic country, with a wonderful culture, and a beautiful state church, I am myself a Greek Orthodox Christian and proud of that.
Greece is like every country I know and has its far share of Good and bad.
don't feel to down about your country or faith, it will eventually get back on it's feet again.
Peace in Christ
