Trump is a fascist.

[Duque de Bragança]

Who are these "actual socialists"?

Those who call for social ownership of the means of production (as opposed to private ownership); you know, the ones who subscribe to the defining characteristic of socialism.

So you don't consider Hollande a socialist?

Not really. Mitterrand nationalized a bunch of industries when he took power, that is a socialist.

Wow, I would never see Mitterand as socialist. You Americans really have a distorted view. 

not really, as Mitterand really was a socialist. Then reality hit him in the face and he had to backtrack on a lot of policies.

Mitterrand came from the right, if not extreme right. In his youth, he even showed up in demonstrations against the "l'invasion des métèques" (damn foreigners invasion). His pro-Vichy period is also well-known, got a Francisque award from Pétain, an award which required "Aryan" heritage. Later on, he went a bit more centre to centre-left à la Guy Mollet (atlantist and pro French Algeria), organised his own kidnapping (affaire de l'Observatoire) during his long opposition period.
Thing is, he did have a socialist spell between 1981 and 1983. In 1983, to cover his severe backtrack, if not outright betrayal, he came up with the idea of using the Front National as a scapegoat and a way to weaken the conservatives. His politician skills were indeed great....

PS: Mitterrand is also one of the earliest examples of champagne left in France.
