I recommend that you research the definition of the word “bias”. Here are a couple from which you might choose:
prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
Or this one:
a particular tendency, trend, inclination, feeling, or opinion, especially one that is preconceived or unreasoned
The very definition of “bias” as it applies to humans contains the notion of pre-judging, unfairness of judgment, or judgment of the innocent. Yet you say this president has “earned it.”
Yes, he has earned it. And therefore it is not bias. What you’re talking about is discernment, judgment.
