It's pathos because he explains what love and hate can do. In his comparison "darkness cannot drive out darkness" because darkness is the absent of light. "Hate can drive out hate" because it will get worse but by showing you care about someone or showing love might change that perspective for that person.
Pathos
"We can never be satisfied as long as their children are stripped of their adulthood and robbed of their dignity by signs stating "For Whites Only".
