No they are typically speaking about opinions sometimes political but sometimes not. One of the most recent ones was in response to The Poppy Wars by R. F. Kuang in which someone commented that the authors commenting on racism in the fictional world was putting in their own opinions and said I quote “real fiction authors used to write without inserting their opinions on every page” which is the review that prompted my post here but certainly wasn’t the first time I have seen this criticism as of late.
