You know what I think? I think Dolph was completely oblivious to what he was saying. Sometimes, individuals are so innocent that they have no idea the context something could be taken. I don't see Dolph as a racist man. I don't see a mean bone in his body. A racist individual would have the ability to stay in his/her lane when they should (open mic radio audience) and would know not to state that at that point. It is the completely non-racist individual who has no clue or it doesn't come to their mind when they are trying to make a reference to try to explain someone's great play to an audience that is listening and NOT WATCHING the event.
I liken it to an innocent small child that has no idea what they are saying, I.E. swear words that they hear but do not understand. Why some guy might have a big nose or something.
I think that some black people are raised to despise white people just like some white people are raised to despise black people. The people who are offended have a very bad opinion of white people so they can't fathom how someone can be un-racist enough to not even make that connection.
Also being called a monkey or an ape isn't what hurt people's feelings. It was the intent and reasons behind white people calling them that that hurt them.
