I don't know how many non-members have commented here, but as an interested outsider, I can offer my thoughts.
My interest is partly in the exclusivity. If I wanted to join an organisation that accepted just anyone, then FM wouldn't necessarily stand out from the crowd. I would've joined years ago had it not been for a rather rogue-ish element that deterred me, and I'm sure I'm not alone in that thought. Having read what I could about FM, in my mind's eye I had a view of what to expect & it was not met. Perhaps it was just that particular lodge, perhaps I had built up an exaggerated expectation, but something didn't tally so I waited.
I have put a lot of time into preparing myself, not just for membership but for doing it the right way, and I don't want the experience cheapened by people who value the organisation for the wrong reasons, or because they don't fully understand the nature of initiation & the role that the Mystery School plays in that.
