This reminds me of interesting statistics that rather surprised GLSEN researchers when they examined data about school bullying. GLSEN is a US organization that offers assistance to school students who want to form GSA clubs, once called "Gay Straight Alliance" clubs, now often called "Gender and Sexuality Alliance" clubs.

The general idea of the clubs, which are student initiatives, is to reduce the incidence of anti-LGBTQ bullying and violence by giving queer and not-queer students the space to come together and support one another, where coming out is not necessary and where participation does not imply a queer identity. (A necessary safety factor for some queer kids.)

Anyway, GSA clubs emphasize tolerance and inclusivity, and GLSEN toolkits include readings on empathy and education about how bullying hurts people mentally and physically.

So, on to the unexpected part:

GLSEN contracts out large studies every two years examining school bullying climates as reported by cross sections of random students (queer and not-queer) filling out questionnaires about their personal experiences.

As expected, in schools with active GSAs, queer students reported feeling safer and less bullied, with meaningful metrics like fewer hospital visits, less need for psychological counseling or intervention, etc.

But what researchers found that surprised them is that all categories of students in such schools reported similar positive outcomes — not just queer students.

Evidently, this is because GSAs are focusing on anti-bulllying and empathy, which of course generalizes to other categories of people than queer people.

That sounds like the kind of world I'd like to live in, and I'm not so sure I'd like to live in the kind of world that the author of the book you're reviewing is promoting. Because I think in his world, bullying would be rife, for all sorts of categories for people.
