I don't think he is promoting being arrogant or cruel and find your comment rather obscure. He is saying things like "learn to say no when friends pressure you to go bar-hopping" and "it's better to be loved by a few people you care about, than to be liked by everyone". Really tame stuff dressed up in foul language. This all sounds like the basic philosophy of Feynman to me.
