Difficult one - if nothing else it would make me realise that freemasonry as an organisation is subject to the hot and cold desires of man the same as any other organisation. However, I don't know if I would know enough from the outside to appreciate that freemasonry is about soooooooo much more than its organising bodies......
Remember the RULE of freemasonry -
Read, Understand, Learn, Enjoy
It would show me that Freemasons are HUMAN and have the same Loves and Hates, Desires and Fears, Strengths and Weaknesses as the rest of us and are NOT Supermen nor Plaster Saints. I vote that it would make no difference to the impression I had preconceived of the Institution, founded in my case on my studies.
