Bi-idiot
Someone who voted for Biden, typically believes that Biden is anti-racist despite all evidence pointing otherwise. Really only voted for Biden because "orange man bad". At most only knows 1 of Biden's policies.
Them: "I don't care if Joe made history for having the most executive orders in his first week. And I don't care that thousands and thousands of people lost their jobs because of him! Orange man bad! Dictator good!"
Any rational person: "You are just a Bi-idiot."
