Whoa... I didn't know states had definitive prohibitions on groups like that. Seems it would violate the right of free association. Not arguing any point mind you, just surprised.
I've thought several times during this recent threat that Obama was not JUST the best gun salesman but that he was probably the best thing to happen for recruitment into both fringe groups and into some stand-up militia's.
