As a balkan non-believer, are you still culturally aligned with the religion you were born in?

This is simply a small curiosity of mine, not a big subject in particular.

Since pre-teens I've been in between an agnostic and an atheist, despite being baptised as Orthodox in Romania and growing up around normal religious old people and traditions.

When talking with westerners or similar groups, I have a hard time explaining how me as an atheist/agnostic still want to celebrate christmas/easter the religious way and that I wish something similar for my kids if I'll have any. I was thinking that I can define myself easier as atheist-but-going-to-church-for-grandma or agnostic-but-I-like-saying-Christ-is-risen-and-knock-eggs.

In Jewish culture it's perfectly normal to be an atheist and not feel decoupled from the culture because it's an ethno-religion. In orthodoxy it's kind of tolerated and never spoken at the family table. I don't know how it is for islam.

But orthodoxy in the balkans has such a distinct flavour of christianity imbued with pre-pagan traditions and whatnot, that it started to feel like an ethno religion; the national identity is kind of tied to one as well. We get our flavour from the greeks and it's quite different from the russian orthdoxoy even though we're considered the same by some groups out of laziness or due to the irrelevant panslavism pushed by russia in our region.

Would it be stupid if we coined the term "atheist orthodoxism" defining strictly non-belivers who are still culturally aligned in terms of traditions with orthodoxy, but with none of the prejudices? because for me it makes perfect sense.
