"Could you please elaborate as to what you mean by a "biased view influencing this promotion"?  There are several possible ways of understanding that statement and I was wondering which way you meant it."
"Shiner - one of the reasons I put you forward is your background with a particular belief system"
Seems a very obscure reason to me!  My comparing it to the freemasons was no big deal, there's no need for a definition of their activities, mate.  We just know that there is a measure of 'mystery' to their activities.  (I have worked with a few, and they would agree).
You don't need to get defensive or 'get it'.  Others will.......or won't 

Does it really matter?
I would have thought Mike had a clearer criteria of who would fit the role than someone simply being tolerant of a minority belief system.  Just my opinion of course, and probably a minority one at that!
In the 70s I believed in re-incarnation and that our previous existence was in Atlantis beneath the sea and Stonehenge and lines of force had something to do with the stars which are now misplaced.  A bit confused...
However, I am now very tolerant of anyone who likes Jimi Hendrix.....oh and Led Zeppelin!  
Does this make me a good candidate? 

Mind you, if you want the role Shiner go for it mate!  I don't think there'll be much competition
