Sites Holmquist trys, and often fails, to go no more than a couple of days without visiting (some of which Holmquist regularly swipes links from without attribution)
I tend to think Uncle Sam is a joke but if that is the case, his/her tactics don't make sense. I mean why bother the people who disagree with those that you are mocking.
It might be important to note that if you go to unclesam.blogspot.com, you will see that the posts are by "anti noam." Back in March and early April there was a blog located at antinoam.blogspot.com that was full of racist calls for genocide against Arabs and Chinese people as well as conspiracies theories about how antiwar.com, Bad Subjects (a publication that I've written for, FWIW), Tom Daschle, indymedia.org, musicians and others artists, Ron Paul, people of color in the United States and basically anybody who was not a member of the GOP and a supporter of the war on terror working together to install "socialist slavery." He encouraged violence against anybody who he deemed an "enemy" of the U.S.
It wasn't really funny but it was so far out there that I had to think it was a parody. I don't know what happened to anti noam or if Uncle Sam is the same person but they seem to have the same ideology. One thing about antinoam.blogspot.com was that it was updated several times a day, IIRC.
