Porco Rosso is both a great film and pretty blunt about its disdain for fascism. 'Red Pigs' was even a nickname for communists used by Italian fascists, and while they remain mostly in the background they're unequivocally the bad guys. I also just found out the other day, a song used prominently in the film, Les Temps des Cerises, was written by a French guy who later dedicated it to a nurse he met during a gun battle when he was fighting monarchists on the barricades of the actual Paris Commune.
