If you want to claim that 99.999% of humanity is biased in one way or the other and that bias is manifest in some way or the other, sure, I'll buy that.
If you throw out the 'baby' because the 'bathwater' is dirty, we part company. I'll accept that there is a selection criteria of facts to check that is subject to bias. And it's fair to propose some other statements that should have been evaluated but were not.
But when confirmation bias and cognitive dissonance comes into play and all evidence is rejected, we leave the intellectual, fact realm, and enter into lower brain structures.
As an aside, one way I judge honesty is how someone reacts when caught lying. Hillary Clinton is a bad liar - she gets embarrassed and has a hard time responding when a lie is pointed out to her. In contrast, Donald is a very good liar by that measure and doubles down on all his lies with a straight face. I prefer someone with a reliable (poker) "tell" .
