Lose your temper and you lose the fight.
The object is very clear in the fight against racism; you have reasons why you're opposed to it. But when you're writing a novel, you don't want the reader to come out of it voting yes or no to some question. Life is more complicated than that.
All stories are about wolves. All worth repeating, that is. Anything else is sentimental drivel. ...Think about it. There's escaping from the wolves, fighting the wolves, capturing the wolves, taming the wolves. Being thrown to the wolves, or throwing others to the wolves so the wolves will eat them instead of you. Running with the wolf pack. Turning into a wolf. Best of all, turning into the head wolf. No other decent stories exist.
In the early fight for women's rights, the point was not that women were morally superior or better. The conversation was about the difference between men and women - power, privilege, voting rights, etc. Unfortunately, it quickly moved to the "women are better" argument. If this were true in life or in fiction, we wouldn't have any dark or deep characters. We wouldn't have any Salomes, Carmens, Ophelias. We wouldn't have any jealousy or passion.
