The subject matter is important and there are definitely a number of good, substantiated claims. However, they are marred by excessive reaching and damaging speculations. I nearly DNFed several times. His bias is made very clear in his patronizing tone. I feel like this won't reach the people it has the most potential to impact, because it lacks the necessary empathy and honesty to foster trust. 

His chapter on spirituality is what I found most compelling, personally, and his rhetoric around gender dysphoria is what disappointed me the most.
