That is BS. (IMHO)
As it has been stated several times here and elsewhere, we are BROTHERS, I was and do talk to any Freemason as an equal. I attended a table Lodge with 3 PGM of the PHA sitting at my table, our just PGM is and was Brother Joe.
If a Lodge tolerates that kind of behavior, they should have an attitude adjustment.
It is bad enough that most Lodges in the USA open in MM, so that EAs & FCs can't attend and that us/them wall is built. (Truth be known, my Lodge is full of 'old' guys who are comfortable with the MM ritual and don't know the others all at well).
