There's no secret or grand mystery about racism.
The Senator explained everything. White people were pissed that they had to pay reparations and
apologize for what their ancestors did, what happened in the past. If this doesn't sound familiar, then a TV show isn't going to provide you any additional insight.
BTW, check out the book
White Rage. it explains how historically, whenever black people make gains, white people systematically enact destructive tendencies to force regression. This show is a proxy for that IRL tendency.
The other "grand revelation" to consider is how, if a person can become a god, what lengths they would go to become one.
Or, put another way, nobody should become a god, because ostensibly, they would abuse that power. As Veidt said, Trieu would make everyone prostrate and kiss her little blue feet.
This is why, even though the show-runners have made an ion-clad tight season, there are sprinkles of potential for another season, with Trieu's mother/daughter, and Angela possibly inheriting Manhattan's powers. Except, her feet are "black" rather than blue.
