Just a little "Worst Of The Web" collection:

American Nazi Party - the usual gang...
Eckankar - six or seven California religions in one
Rosicrucianism - this one's been around for decades; get a load of the "creepy temple organ music" (the site's term for the sound cut, really!)
NAMBLA - the National... oh, forget it
ARC - gay white racialists
Nazi.org - Libertarian Nazis? Does anyone know if this is a hoax?
QSB - Queer Skinhead Brotherhood
