“Free”?
Or “Republic”?
Go look at the main page, especially the paragraph of blue & red links at the top or the Popular Keywords in upper left. Eg:
"Popular Keywords: 113th banglist budget catholic communism communists conclave coup democrats economy education electionfraud guncontrol guns homosexualagenda military obama obamacare palin randpaul secondamendment sequester talkradio votefraud voterfraud"
My #1 guess is that "homosexualagenda" was the trigger. Anything other than "gay" is a Thought Crime these days.
