I find it way way more useful to have such lists which allow new people not to waste hundreds of hours of time and hundreds of dollars on books that will confuse, mislead and trip them up. After laying the groundwork with mythology, history, and popular books written by ethical experts in the field, one can return to the problematic books with the tools to discern if they wish, but by then hopefully they would be advanced enough in their work that they wouldn’t need to.
Secondly, I think it is wrong and bad to keep sending money to publishers and writers who produce junk, problematic, unethical junk. The value of these lists with good books and bad books is to reward those who are ethical accurate and helpful with sales and positive attention.
The one or two ideas of worth in the poorly done books are generally also in the good books, times a hundred! Why not spend time and money reading a good book with the few decent thoughts from the bad books in it with out the crap, unethical, misleading and inaccurate crap.
There are bigoted, racist, homophobic authors I won’t even speak the name of. There are authors who spread lies and misinformation that harms the community. I won’t even talk about their books.
I personally think this is the better route. Although I don’t argue with those that make the lists of books or publishers to avoid, because I hope that there are more people who want to boycott bad material than those who want to support it.
