I note that the other thing that bothers me about that assertion is it's assuming the wrong population, which is just bad statistics. I read more books by women and PoC than by white dudes as a deliberate choice; any comments I make about books I've read will therefore be disproportionately about WoC authors relative to the demographics of new publications. I continue frustrated that the report makes no mention of this; misleading use of stats weakens it.
