"Your priest is deliberately excluding the congregation from what he is doing."

I'm sorry, but this makes no sense. Why does the priest need to *face* the assembly for the assembly to be included? Does the assembly have to *see* the priest's *face* to be included? Why? 

Does this mean that people who cannot see -- at all -- are excluded? What about people who are sitting behind a pillar? Or who -- regardless of which way the priest is facing -- aren't even looking at the priest? If someone attends Mass, and follows along in the missallette, or prays with eyes closed, or is attending to a child -- is that person "excluded" -- because s/he isn't looking at the priest's face?

Why do you consider which way the priest *faces* so terribly important?
