I would appreciate not being thrown under the bus just because you cannot believe that it’s possible for a non-mentally ill person to be an ASSHOLE. That is all it takes to be a racist or a murderer or a rapist.
As to diagnoses: if you* are a mental health professional you presumably know not tho diagnose a public figure (unless, perhaps, they are a clear and present danger to the entire world like President Trump), and if you are not one such then you don’t know enough.
You can’t teach schizophrenia. You can’t teach manic-depression.
* I mean here the general/generic you.
