The Freemasons are invitation only.

Well mostly false... In the United States and most other jurisdictions, invitations to join are never issued by anyone ever. If you want to join you must ask. In a few parts of the world, particularly where masonry is subject to persecution from hostile regimes, it is indeed invite only. That being said, there is much more to joining than simply filling out an application. Just as anyone can apply (in most jurisdictions), anyone can also object thus forbidding your application.
