Gee, that opinion kinda flies in the face of the kind of attitudes and stories that the news outlets put out. In fact, it's a bit different than what I was taught in school growing up. School had me thinking there was two kinds of militia; the good kind that helped our country escape British rule, and the bad kind that existed these days like the Posse Comitatus which lives without disregard to common law and decency.
I guess I had a pretty good education because I now know the difference and similarities between the militias of past and what exists today. For the most part they exist to protect what they believe in, for the most part to take care of those who would want to relieve us of our rights.
Of course not all militias are as such, some (like a lot of government officials) use the constitution to further their own agendas.
