Where the severe unnecessary human-caused suffering of A negates the lesser abuse of B, thereby, by implication trickeration, justifying the actions of those abusing B. In other words, if someone is spitting on you, the Dawkins fallacist will emphasize the fact that somewhere else, someone is getting punched. If someone's punching you, someone else is getting whipped, etc. All of this serves to silence the abused party and functions as a defense of the lesser offender (the spitter).
The reverse Dawkins fallacy (false equivalence):
Where B equates its own abuse to A's without recognizing the difference in severity, generally in order to advance its narrower interests while leaving the more abused behind. B uses A, is yet another abuser of A.*
*Every time I talk about Japanese racism, I worry about assumptions of reverse Dawkins. I want to say the basic inside/outside structure works the same where Japanese are the inside, dominant culture, that white supremacy isn't so special, that Japanese racism is structurally of a kind with it, while making clear I'm aware of the differences. I did do a couple nights in jail thanks to racial profiling, matter of fact, but still, for the most part, it otherwise only rises above annoying when it comes to my "half" kids. No one needs to worry about me personally on the racism victim front, though Japanese racism isn't without its victims (non-whites have it worse and some white people may as well). It's in any case an every day window for me into how racism works.
