Other than William Joyce, none of the people mentioned on this thread were Nazi sympathisers or fellow travellers (even Mosley is arguable, his views were much in line with Mussolini's corporaratism than with Hitler, anti-semitism was one of the few areas where he was closer to Hitler).
As someone whose had the horrid curiosity to pay for access to the archives of Action and the Fascist Weekly online, there is absolutely no doubt in my mind that the entirety of the BUF from Mosley downwards is irredeemably and entirely Nazi sympathising and that the distinction between Italian and German fascism that people find so important nowadays for various reasons was simply something not many people made in the period, especially not in the British Union of Fascists and National Socialists.
