Even though the comment is removed now, I’d like to add that equating social democrats with fascism, i.e. ‘social fascism theory’, kind of lead to the disunity in the fight against the NSDAP from the communist side (KPD). This is not supposed to downplay the actions of the SPD during and in the emergence of the Weimar republic, but ‘social fascism theory’ didn’t help 1930s antifascism nor do I think does it help 2020s antifascism.
