That is such a self evidently ridiculous statement it hardly deserves rebuttal. So rather than bother myself I asked ChatGPT to respond. It said:-
“Mosley’s ideology was directly opposed to the principles of Antifa.
- He fought against anti-fascist demonstrators (e.g. at the 1936 Battle of Cable Street, where Jewish and left-wing groups confronted his Blackshirts).
- Antifa’s militant anti-fascism emerged historically as a response to leaders like Mosley.
👉 Therefore, the statement “If Mosley were alive today, he would support Antifa” is extremely unlikely to be true—almost the opposite of reality. If anything, Mosley would likely be the target of Antifa’s opposition.”
