> In fact, the claim that “bias can be avoided and should be absolutely”, that is implicit in your resposne reflects a bias of its own: a bias toward moral or intellectual purity, as if the parent recognizing bias is equivalent to endorsing it.
Nonsense. Your definition of the word "bias" includes any assertion whatsoever. Bias is distortion from reality and truth. Saying that we can avoid distortion is not itself a distortion. I never claimed that all bias should be avoided, but the post I responded to said that bias can't be avoided.
Also,
> a bias toward moral or intellectual purity, as if the parent recognizing bias is equivalent to endorsing it.
There is no conceptual connection here between "purity" and the equivalence of recognizing bias with endorsing it, nor is saying "bias can be avoided" related to, or a kind of, "purity" in any useful sense. Stop using abstract words for effect and speak simply.
> I get that this is a pedantic point to make but to come at the parent with such vigour for being realistic, again seems a bit unfair
If the parent were being realistic, they'd say that we can't even recognize bias, which is actually more agreeable to me. But instead the parent admits that we can recognize bias. Since we've gotten that far, then I can say that failing to avoid it, when we should avoid it, is merely a lack of will and integrity rather than some inescapable fate.
