The above linked article is written by a woman whose bookclub kicked her out. Reading the article, it seems like the bookclub was never a good fit for her, and the organizers of the club pushed her out. Missing meetings for going out and living life, and disagreeing with the organizers were cause for her being pushed out.
I love discussing books when others have a different opinion than me, or than others in the group. It makes for a discussion, rather than, “me, too” comments. I guess the organizers of this club would rather only have members who agree with them? It sounds like a boring bookclub.
