I certainly won't speak for Addicted2weasels, but I, and I think the Orthodox, would absolutely agree with what you said. I am LCMS, but spent some time learning about the Orthodox and really gained an appreciation for their Traditions and have tried to incorporate it into my LCMS life.
I attended an Orthodox Catechism Class and I asked a similar question, and this is the response from the Father who was teaching the course:
>Holy Tradition is the whole Faith, the life of the Church. It is distinct from "human tradition," human-derived religious teaching. Tradition is also different from the many cultural "traditions" and customs. That Christ was born of a virgin is Holy Tradition. That we put up a Christmas tree is tradition.
>With regard to Holy Tradition, we see it in the Bible. All that is preached and taught by the Apostles is Tradition. The Bible, containing the written record of all these things, is Tradition. All that is not recorded in writing is also Tradition. As St. Paul said, "To this He called you through our gospel, so that you may share in the glory of our Lord Jesus Christ. Therefore, brothers, stand firm and cling to the traditions we taught you, whether by speech or by letter." The Church compiled the Scripture and has preserved its interpretation since ancient times. We know what is Holy Tradition because it is affirmed by the Church, the pillar and ground of Truth, which is guided by the Holy Spirit today as it has been since Apostolic times. We can see the stream of Tradition in the ancient writings and in the same Faith held by the Saints throughout the ages.
>Protestants can ask, "How do we know Tradition outside of the Bible is true?," but how do Protestants know that the Nicene Creed (based on a particular interpretation of Scripture) and New Testaments table of contents is correct? These were affirmed by the same bishops who held that the Bible is part of Tradition. In fact, those books placed in the Bible were in harmony with Tradition.
>To better understand the Tradition, I recommend Chapter V of Fr. Georges Florovsky's classic work on Bible, Church, Tradition. (The entire book is great.): http://bulgarian-orthodox-church.org/rr/lode/florovsky1.pdf
>If you want to read more on Tradition and Bibilcal interpretation, I also recommend this book: https://www.amazon.com/Souls-Longing-Christian-Perspective-Interpretation/dp/0990502961
In addition, Paul actually references the Church as the "pillar and foundation of truth." (1 Timothy 3:15). This of course makes sense because the Bible did not exist at that point in time.
