Don't quote me on this, but I don't think there are any anti-masaon "groups," there are just anti-masons.
As a side note, seeing how you have just turned 20, I suggest that you contact a local Lodge and get to know some Freemasons in your town/city. This
way you will not need to go through the getting to know you part in a years time and you can petition the Lodge on your birthday or the month before.
Don't worry about Freemasons, they are all pretty nice fellows.
