The Masons believe that one deity is all deities, all deities and religions of the world are equal, so that is why strong denominations disclaim it. Most presidents have been masons and if you watch, a lot of folks have the mason stickers or glue-ons on the back of their cars. Apparently they feel that a policeman who is a mason will overlook their offences since they are fellow masons. Supposedly masons can recognize each other without a handshake but also by the handshake. I think I have the non-handshake figured out. Too much secretive, male symbols, rituals and foolishness to be more than an organization to link folks together as a source of connections and power.
You can read up on the group in a book, "Kingdom of the Cults". I am sure that there are other books and information, too.
