If I could put in my two cents here...
I'm not offended by your denial of the invisible church, in fact, I mostly agree with you. What does put me off is your vehemence that the Orthodox Church is the ONLY visible church, plus your assertions that a certain statement is correct because the Orthodox Church says so, with no sources to back up the claim. I admire your devotion to your church, but I came to CF wanting to learn more about the Orthodox Church, and your attitude is turning me away from Orthodoxy rather than pulling me toward it.
To the others who've been more open in discussion:
