Reading Domestic Enemies right now, written by Freeper Travis McGee and recommend it highly. If you haven't read Enemies Foreign and Domestic and Domestic Enemies, you're really missing out on some good stuff - very topical and scary plausible.
Just completed The Right Winger's Guide to the Radical Left, which is pretty funny - and also by a Freeper. It's a great list of the Usual Suspects and well worth reading.
