Biden's public persona of being a doddering old fool undercuts what he also is: an easily angered and self-destructively stubborn man. He has always devolved into a threat-maker and insult-thrower by the slightest criticism, whether from a journalist or a member of the public.

Whether it's "Listen, fat," or when he threatened to throw a guy's phone or when he responded to a black news anchor asking him about cognitive tests with something like "Why don't we make you take a cocaine test!" Biden is exceptionally ornery, and incapable of being reasoned with when in that state.

That is why there was that expose article about how Biden's inner circle is neolib/neocon lackeys like Joe Scarborough and Larry Summers, while savvy staffers more cognizant of his actual perception by the public are reluctant to clue him into any upsetting realities, lest Biden chews them out and sidelines them.

I know that ex-Trump staffers said that Presinald Trunt would often outright shout that he was going to have them executed or jailed, but I think the impotent cartoonishness of such threats is less menacing than when Biden gets in your face and grits his teeth and growls out in hushed tones a genuine and feasible consequence.
