Amen to that.
Inflation is too many dollars chasing too few goods. The inflated dollar has less purchasing power. The same rule applies to rhetorical currency. When too many "racisms" chase too few sins, each "racism!" has less purchasing power.
Maybe because I'm Jewish, I am jealous of the word "racism." I think it needs to be protected from devaluation. Racism is wishing someone ill on account of their ethnicity. The Klan is racist, and Mr. Kendi is racist. Anything else is something else, and the Black activists' effort to attach the word to anything that bothers them is misguided.
Today I saw an article in Medium that calls a bank "racist" because it won't give credit to felons. According to the author, racism accounts for Black people being felons, so if a Black felon is denied credit, the bank is "racist." The word now does so little precisely because it is trying to do so much. Too many "racisms" chasing too few sins. Mississippi does have a history of racist lynchings. But if "racist" covers every unfair aspect of being Black in America, maybe lynching wasn't so bad after all. Only, it was bad.
"Microaggression" is an accurate word to describe the slings and arrows of Black America's outrageous fortune. But it isn't very poetic. The medical field gives us the word "microtrauma," those little shocks that human flesh is heir to - what jogging does to your knees, etc. But even "microagression" can inflate to meaninglessness. My grandmother once said to me about political corruption "When you sit by a full bowl, you eat. (It rhymes in Russian.)" If you tell people not to overuse "racism," they switch to "racially insensitive," or some such, and then they overuse that.
"Playing the race card" means trying to spend a constantly devaluing currency and devaluing it in the process. It seems like a good idea at the time, but in the end, only what works (with due regard to its externalities and precedential impact) is worth doing. Calling too many things "racist" doesn't work. Maybe, as Ms. Latting the social Justice strategist suggests, something else will work better. In at least some contexts, Aesop was right and relevant: Gentleness succeeds where rudeness (an r-word) fails.
