Why on earth would you want to be friends with someone like that?
He needs to hear this: "I just can't understand that level of hatred to someone who has never done anything to hurt you."
He shouldn't have his boorish, ignorant behaviour encouraged or condoned.
Personally I've long since cut people like that out of my life, but seeing as you haven't maybe you should ask him one day why he thinks it's okay to be such a jerk.
