I’m not particularly political and am also not a historian but I don’t think it’s necessarily correct to equate the literal text of the manifesto with the principles and practices of fascism.

The message of universal suffrage vs. that of preventing an out group from “stealing” an election are not far apart semantically. Same with workers rights - in practice the worker protection laws that were passed in Italy at this time were so full of loopholes and qualifications that ultimately the workers do not gain power in that system.

It is this fair, in my view, to question the spirit of the manifesto in the first place.
