No. Like many clubs, societies and business corporations, Freemasonry has aspects that are private to its members but are not secret.
This is evident when one considers that almost every country in the world has a Grand Lodge of Freemasons and each has its own public web site. Freemasons freely wear rings and other Masonic ornaments, Masonic buildings, which often give a tour of their premises to the public, are clearly marked and their addresses can be found in the Yellow Pages, and in some countries cars have Masonic licence plates and bumper stickers! Moreover, libraries carry many books on Freemasonry.
If Freemasons are secret, they need a refresher course in camouflage! Nevertheless, the “secrets” or private aspects of Freemasonry can be classed as grips (handshakes), passwords and signs which function as modes of recognition. Practically every other aspect of Freemasonry can be aired in public.
