Everything from the John Birch Society (which wasn't well thought of in those days) to writings by and about George Lincoln Rockwell, founder of the American Nazi Party.

I wasn't particularly impressed, but one thing struck me. Most of them, for all that they claimed to admire and adhere to American values, believed those values were fragile. One foreigner spoils the population of hundreds of millions. One foreign word spoils the language. One alien idea spoils the creed. One drop of unwanted blood spoils the line. Fragile. Frankly, if I had a .45 automatic that was that fragile I wouldn't bother trading it off, I'd throw it in a lake, somewhere.
