What exactly is "Celtic culture" today, though?

I guess Irish culture is what comes to mind.

The Irish are Catholics unlike Protestant Germanics.

Russians and Georgians are also Christian orthodox, so? Romanians and some Siberian peoples are orthodox, so? What does it have to do? Celtics are western people, they are closer to Germanics and Romance and those have been influenced on each other for many hundreds years unlike Slavs. It is the west, whether you like it or not. Slavs are other side of Europe, whether you like it or not. Poles were, are and will be aliens in the western world, whether you like it or not.

Georgian cuisine is also quite Non-MENA to me.

Celto-Germanic is what I am but interested in? Celto-Italic and the western and southernmost Balto-Slavic.

Disagree. Georgian culture is similar to other Caucasus(non Turkic and Indo-European) peoples, the religion has nothing to do with culture.
