Axiom

No story about how a particular practice is unjust that is short enough to be read and digested is long enough to be discussed.

Someone will either open a round of misery poker out of feeling that the omission of any mention of crimes against their group denies them well deserved victim credibility, or start the cataloging of sins to satisfy themselves that those who trespassed against them won't "get away" with anything. Whichever one it is, the discussion will be sidetracked into a tit-for-tat discussion of individual wrongs and perhaps justifications.

The only way to avoid this is to have such a comprehensive catalog of individual incidents of injustice that it would effectively be infinite.
