As has been pointed out, you are most probably already in a militia.
One of the bad things about militias is the tendency of the idiot sub-genus to describe their paramilitary forces as 'militias'. It doesn't look good when WAR and the KKK describe their small armies as 'militias'.
And, of course, guess who the Media will focus on and interview when they do their segments on militias? You guessed it: The Church of the Apocalypse. *sigh*
Plus, the situation with militias today is similar to the situation of the American Nazi and Communist Parties during World War 2. I've been told by several sources that the American Nazi Party would have folded during World War 2, if it hadn't been for the vast number of undercover Federal Agents paying dues.
After the OKC Bombing, you can bet vital portions of your anatomy that the 'increase in Militia Membership' so breathlessly reported by CNN was more than partly due to undercover agents.
And then there are the Ice Cream Commandos. No matter how intelligent, loyal, patriotic or whatever your militia, you're going to attract the 22 year-old-Vietnam/Desert Storm Veteran, with the "Kill 'em All, Let God Sort 'em Out" t-shirt, the Rambo(tm) serrated, crew-served knife tucked into his Nike combat boots, and the Desert Eagle .50 CCW inside his black BDU trousers. He's easy to spot: when you have a meeting about peacefully picketing the Million Moron March, he'll be whipping out the pipe bomb instructions (downloaded from the Internet)and assembling the devices on your kitchen table. He'll also be the one signing your militia name to the 'anonymous' death threats he regularly sends the President. Even after you kick him out. *double sigh*
