'''David Horowitz''' was an activist in the New Left movement in the 1960's and claims to have been "a lifelong civil rights activist". He was editor of an anti-Vietnam war magazine: ''Ramparts''. However, currently, Horowitz is known to side with corporate interests and conservative ideals, and is frequently best described as a [[neo-con]] -- the term of derision that the left uses to describe Jews who have rejected Marxism. He is now a "lapsed leftist" [http://www.mediatransparency.com/personprofile.php?personID=15]. In the 1990s, Horowitz hosted several ''Second Thinkers'' conferences where ex-leftists who recanted or underwent epiphanies could network with fellow travelers. Several of these second thinkers are now neo-cons. Christopher Hitchens was a regular participant at these conferences, and today co-organizes events with Horowitz, e.g., tour of the UK where he features as a speaker [http://www.frontpagemag.com/Content/read.asp?ID=90].
David Horowitz was a speaker at the 2003 [[Conservative Political Action Conference]], which reads as a who's-who of the conservative and [[neo-conservative]] movement.
