The "so-called" is not snide or uncharitable either. It is confusing. The Orthodox Church is Catholic and Apostolic, and it is Eastern. How can there be "another" Eastern Catholic church? The same goes for the so-called "Greek-Catholic" church in Ukraine. It is not Greek, for sure. And the Greek Orthodox Church is fully Catholic, so what is a "Greek-Catholic" church? The term "Uniate" leaves no ambiguity as to what churches wer are talking about.
Perhaps you need to work on your sensitivities and not read into things
I might well consider the Serbian Church a "so-called" Orthodox Church. But it would be snide and uncharitable of me to refer to your Church that way
You certainly may! But, I hope you realize that you will be laughed at by the Orthodox as well as the Roman Catholics.

You know, I think it all started with the first Holy Roman Emperor at Aachen. There was already a Roman Emperor. And then Charlemagne came along and got the Pope of Rome to crown him Emperor of the Romans. What an absolute crock!
