In light of Foucault's laborious tomes which concurrently disect and confound the relationship between the individual and Western power structures (think Discipline and Punish) his support of any anti-Western liberal regime is somewhat predictable. It is equally an example of the academic mindset which, despite being physically present during the lead-up to the revolution, is constantly contextualizing the very real events--with very real human consequences--in terms of history and theoretical models. It's indoorsy at best and at its worst, despite the claims of studying and elucidating human experience in the hegemonic soup, completely removed from the actual truths over which they demand to be recognised as experts.
On a lighter (?) note, given his keen participation in the San Francisco S&M scene, perhaps he really was practicing what he preached.
