I am ok with Orthodox Christians rejecting Catholic positions. I don’t always like to hear about the details of that 24/7. I don’t make it a point to tell a Protestant I think he or she is heterodox because they reject the Eucharist. I go out of my way not to talk about ‘sensitive issues’. This is not to say I don’t think Protestants are heterodox because they reject the Eucharist. It is a rejection of Christ. But if I say that or even reference it to an Evangelical I am just going to start a dispute, alienate him/her. I would rather try and find common ground. Steer clear of the elephants in the room.
I feel like Orthodox Christians always start in on me about the Pope. (I actually agree with a lot of it myself; don’t need to hear it; this never occurs to them as a possibliity.) The Pope is maybe (at least to me) one tenth of what it means to be a Catholic. The Orthodox think it is everything. They project a straw man onto Catholics. (they are infinitely more obsessed with ‘scholastic’ theology and abuses of logic than any Catholic I think I’ve met and/or read in my life, and that includes Thomas Aquinas, who, incidentally, did NOT think you could know God through logic) Nine tenths is about Scripture, Tradition, the Liturgy, the Liturgical Calendar, the Sacraments, prayer, the Rosary, the Saints, the Church Fathers. I get that a lot of the history of the Church is problematic - schismatic between East and West. Because I know all that and worked out my opinion on all of that years ago, it bores and irritates me when people start in on it. Same with Catholics trying to get the Orthodox back in line with the Pope. Drives me up the wall. Enough already. Let it be. Treat the Orthodox with respect as the Orthodox. This is just my opinion mind you. Full disclosure I am half Orthodox/half Catholic - make that 65/35 Orthodox.
