supporters. Had you taken just a moment to check credible sources (see link) you wouldn't have made the mistake of saying he's not a practicing psychiatrist...and you might have realized that academics in all fields write books about what they know in those fields.
For normal persons, it's unreasonable for them to support proven Immoral, Unethical and Criminal leadership...and yet a significant core of Americans continue to do that with Donald Trump. Dr. Razzaque's analysis fits with what many people I know see as a common thread with MAGAs...Fear, Anger and Hatred toward others...it's who they are...it defines them...and having someone as President publicly voice those feelings "VALIDATES" their view of the world. Consequently, they'll never stop supporting him.
Sadly, this mentality is a departure from reality and borders on psychosis...which can't be cured...only managed to varying degrees...often through medication. (not my finding...it's from someone trained in psychology).
