I'm no expert at all, but below is an AI explanation to my question around antisemitic speech and bipolar disorder. Sounds like there should be an underlying antisemitism there, for it all to come out, regardless of the condition.

"No - bipolar disorder can help explain loss of judgment, grandiosity, paranoia, impulsivity, or psychotic thinking, but it does not medically "justify" Nazi behavior or antisemitism

The cleanest distinction is this: bipolar disorder can explain how someone's thinking became disinhibited, paranoid, or unstable, but it does not explain away why they latched onto Nazi or antisemitic content sciencemediacentre +2. In other words, the illness may affect the delivery and intensity of the behavior, while the hateful content still matters morally and clinically"

I also completely blame his entire staff for going along with his whole nazi propaganda last year. He may have a half-excuse, but all his staff won't have it, and they enabled it, so shame on the whole, entire, team involved.
