The Rutherford Institute

For those who have never heard of it, The Rutherford Institute is dedicated to defending U.S. civil rights. Unlike other groups that claim the same (and are better televised), Rutherford dose not support a political bias.
I found that this article about the Second Amendment is one of the best written I have read. The article uses facts and the founding father's own quotes to prove their point. It then shows how both political sides of the issue are getting it wrong.

If you are liberal, conservative, or somewhere in the middle you should check them out. No political bias, and actually trying to defend ALL American's civil rights.
