I saw this mentioned in another thread, and thought I would start a new thread about it. I know that membership in the Freemasons, and it's affiliates like the Shriners, is absolutely incompatible with Catholicism and is sinful. What about other clubs, however? Something like the Lions, The Rotary Club, the Eagles, Sons of Italy, etc. As far as I am aware, there is no connection between these sorts of organizations and the Masons, nor is there anything "secret" about them. Rather, it seems to just be a group of people (usually men) that eat and drink together, and occasionally do a charitable event.
