Henry Ford also wrote a series of books titled “the international jew” in which he spew antisemitic shit and crazy conspiracy theories.
He had his own newspaper to publish anti-semitic ideology. High ranking German Nazis including Hitler considered him an inspiration.
Saying he was “just the Elon Musk of his time” falls on short on how fiercly Ford was anti-semitic, how he systematicall contributed to the ideological framework for anti-semitism and spread it among the Americans and the people in the world.
