It's great, if troubling. I wasn't taking some of the cultural shifts very seriously until reading it. Very few books shift my thinking on current events so significantly.
I should order that! I emailed him after I read The Righteous Mind (2016, 2017 maybe?) asking what his opinions were of the shifts we had seen since the book was published and whether his opinions have changed and how hopeful he was, etc. He did take the time to reply, even if it was short, and answered my questions; always appreciate when an author interacts with readers like that.
