"Jehovah your God...treats none with partiality."--Deut. 10:17.
"Impartiality is one of Jehovah's endearing qualities." <--Yes, between that and his tendency towards genocidal warfare, I don't know what makes me love him more.
"What does it mean to be impartial? It involves being fair, free from having or showing bias or favoritism." Fair. Like condemning an entire race to death for the actions of two people. Letting people beat and murder your favorite son to save the same aforementioned race from your own punishment!
Free from showing bias. Like not preferring one nation over all others for the majority of human history, for instance.
So...I'm trying to figure out how exactly Jehovah even remotely fits this definition.
"Hence, one who is impartial will pay due regard, not to an individual's outward appearance or circumstances, but to his or her character as a person." <--So can we explain again why wearing a sportcoat and slacks at a meeting if you have a talk is generally frowned upon by people imitating the 'impartial' God? Or why women shouldn't wear pants? For the same reasons said God doesn't qualify as impartial. He's not, and they're not.
Fair. Like forbidding any audio or video recording of judicial committees held in secret, for example.
I could go on, but it's clear that neither the Watchtower nor their god can be properly called impartial.
