I think my friend hates black people?

He's mexican but he "claims" he's Mayan or something. Once we were having a conversation and somehow we had a conversation about African-American(I said how I have alot of friends that are African-American and I dated one) and he said he don't have one single friend that's african american cos he don't like/trust them. I told him how theyre not all the same. He kept going on how he will never let his daughter(if he has one in the future) date an african-american dude or befriends them. I got very mad cos I grew up with a lot of African-americans. I get along with them. He told me that I should stay away from them and how they are bad people etc. Once I recommend a song by bruno mars and he said he didn't like it and I asked why? and he said not my type of music and he's black. I said He's half black and mexican(I think) and he just said i still dont like it. The only african-american he trusts is his friend in the army. What should I do about this?
