There seems to be an attitude, at the moment, for authors to defame, abuse, harass, and denounce, book bloggers for giving them 'bad' reviews.
Now, I'm not going to go into the semantics and the 'he said, she said' of the thing. But I am going to make some comments regarding fair and critical reviews.
Because this isn't something that's new. It happens.
Unfortunately, it seems to be happening with increasing frequency, but that's another matter.
Those of us involved in the Diversity Movement are probably the least surprised. Diverse reviewers tend to be the first in the metaphorical firing-lines.
