Dont sign anything. Pledge whatever loyalties you want, but remember this: signed paperwork ALWAYS gets uploaded to a computer database, and today's databases are housed in the cloud. ALL computers have backdoors that allow GOOGLE to read what is there. The CLOUD is pretty much owned by GOOGLE, too. So, sign the paperwork at your own risk. A truly patriotic militia type group will already know this and won't force anyone to sign a damn thing. Verbal pledges are King in this respect. If they don't let you join because you won't sign a written pledge, then call them out and leave the group.
