Honestly, this dismissive comment helped me formulate a thing in my mind.
So, as a Black American, I do believe it's important to hear from the voices of people who are suffering.
That being said, I find that, unfortunately, that market-in-books tends to really lean into the suffering, and I say it's important to consider the extent to which that might weigh down the writing and the reading experience.
This is the primary reason I bristle at the idea of "getting away from e.g. white male writers." There, of course, is nothing inherently better about them; but our unfortunate social / cultural / historical filters have made it so that (easily findable) writing that is free from certain kinds of suffering comes from them -- and sometimes you need that too.
