That's not an opinion commonly held by the Roman Catholic contingent. They include the Orthodox as Catholic capital *C*.
So, take it up with them.
You are Catholic. You posted a Prot hit piece. My comment stands.
Only those in the 23 Eastern Churches. Those not in communion with the pope (the author and OP, for example) aren't called "Catholic" under most circumstances, if ever.
But here's a fun fact -- the Orthodox are still properly called "the Orthodox Church" and have valid sacraments. No other non-Catholic assembly qualifies as a Church or possess the sacraments.
No matter what kind of orthographic games you play, the Orthodox are not in communion with Rome, nor is Rome in communion with them.
If you bother to read the original posting (and can figure out what it's saying with the UTF-8 or whatever those strange characters are supposed to be), it's basically taking the usual Orthodox tack of slamming Rome and Protestants together as two peas in the same pod.
