I had a great experience when I was part of a lodge. I'm atheist and so could join a Droit Humain lodge in France (which does not require belief in a Great Architect of the Universe and is mixed). I'm now in Hong Kong but unfortunately have failed to find a lodge that doesn't require a belief in God and that is mixed (I refuse to go to a male only lodge).
It's a pity because I found freemasonry to be hugely beneficial in terms of friendship, interesting discussions and support.
