It takes an authoritarian regime to be fascist, but not every authoritarian regime is fascist. Most of the dictators you mentioned don't have the corporatism that is one of the central tenets of fascism. Others lack the collectivism. Others like the populism. Some are simply petty thugs with no real ideology.

Granted, a state can be fascist and a kleptocracy. But it seems fairly clear to me that by the time the Duvalier's voluntarily went into exile that virtually all the fascist elements of the government had decayed into chaos. If MNS has listed Francois Duvalier, I'd probably not have crossed him off the list.
