I wonder if it includes advice on objectivity:
Hide your bias by stating that you’re unbiased. Those who agree with you won’t notice, as they’ll be feeling emboldened since their opinions are being described as facts. And those who disagree will appear to be the ones who are biased. Then you don’t need to provide evidence to disprove them. You’ll only have to say that since you’re right, and they disagree with you, they must therefore be wrong.
And he probably has a few words on dealing with conflict:
If someone disagrees with you and the above tactics fail, insult them and tell them repeatedly to shut up. As long as your voice is louder than theirs, you’ll be the one who gets heard. In the right setting, there may also be the option to simply shut off their microphone.
It could be worse. Imagine if Ann Coulter wrote a children’s book. Actually, don’t imagine that. Her adult books are hellish enough.
