your friend's use of the word "hate", which you see as:
- refreshing "directness" VS passive-aggressive 
may be seen by some as one or more of the following: 
- emotional reaction against an entire work VS taking the time to compose a well-articulated intellectual response,
- thinking out loud VS having a filter, and boundaries,
- shooting from the hip VS caring enough to think and process beforehand, 
- rigid thinking VS flexible thinking, 
- close-mindness VS open-mindness, 
- gravitating toward the negative VS being able to find the good, 
- attacking VS being vulnerable in discussing perspectives,
- out-of-control rant VS normal give-and-take of asking questions & listening to others,
- lack of skill to deconstruct and analyze VS having acquired and practiced the skill of deconstructing and analyzing, 
- not interested in finding commonality and areas of agreement VS genuinely liking the other book club members, 
- lack of social skill and theory of mind VS demonstrating equal interest in what others think and why,
- a conversation ender [color:#999999]VS a conversation opener
Possibly best done by exploring ones' thoughts internally, then using a filter
LOL,  indigo... I don't know but this sounds a lot like what the author is railing against in the article and in the interview I saw with the author of another article in the same vein and quoted in this one - Caitlyn Flanagan!
