Answer:
Prejudiced non discriminator
Explanation:
According to Robert Merton's typology of prejudice and discrimination, people are either prejudiced or non prejudiced (this refers whether they have some preconceived opinions against people) and either discriminator or non discriminator (this refers whether they actually act in a discriminatory way or they don't)
In the example, the coach does have prejudices because he dislikes African Americans but he doesn't act on them because he still hires them, therefore he is a non discriminator. Thus, he is a prejudiced non discriminator.
