"Nope, I hang my hat on the fact that, right or wrong, the trier of fact appointed him guardian."
So, if some future "trier of fact" decides that left-handed people are defective and orders all left-handed people starved to death, that'll be just hunky-dory with you?
And then when he starts "finding" that the right-handed enemies of his campaign donors are actually left-handed, you won't have a problem with that?
"that is part of the price of having the best legal system ever designed"
We don't have it any more, as this atrocity demonstrates very well.
