And this is a poor pool to select data from as the people here are orthonerds.
What is an orthonerd? I do notice that several identified their assertion that the Catholic Church is all about apparitions as having come from a college or university campus environment...I did note that. But is that what orthonerds are? Student converts?
I mean that people who tend to frequent forums about a particular subject tend to be much more well educated in a formal sense about the subject the board is about than others who do not.
Not only are participants on boards more educated in the subject the board is about, they also tend to have much more zealous or rigidly held beliefs or stances on the subject the board is about than most others who don't hang out in such areas.
I doubt the women who work in the cafeteria here at work who are all RCs and spend most of their time working, doing charity, and raising families have thought a lot about the filioque or would even care that EOs don't include it. They are salt of the earth. Humble and hard working. One of the women noticed my eating habits over the course of the year and asked if I was Jewish. I told her I was an inquirer in EO. Her reaction: That's great! I don't know a lot about them, but I know they have more rules about eating and are more strict on some things.
She is praying that I am received into the Church. I doubt she gives a fig about the filioque.
Now the Jesuits I stayed with, I am sure would have some strong opinions.
