As what I can see is that Maxiong is sharing interesting informaton with us, and he didn't provide his own opinion about what he brought up--he is just stating the facts which seems pretty interesting, at least it holds my attention. However, from your post to his you say Maxiong is prejudiced, judgemental, and reading makes him not happy, he deson't respect other people's value...I don't get it. So that is why i think more crdible evidence is needed to support your statement, or readers won't be convinced.
In the English language, black sheep is an idiom used to describe an odd or disreputable member of a group, especially within a family. The term has typically been given negative implications, implying waywardness.[1] It derived from the atypical and unwanted presence of other black individuals in flocks of white sheep.
In psychology, the black sheep effect refers to the tendency of group members to judge likeable ingroup members more positively and deviant ingroup member more negatively than comparable outgroup members.[2]
