Which one of these 4 examples is Racist?

none of the above. A black man kills a white man because he's white. That is racism. America needs to stop using racism as a crutch to get something he/she wants but doesn't deserve., "Oh, that Mexican looked at me funny. He must be Racist." " I didn't vote for Obama I must be racist." Let's grow a thick skin before it gets more out of hand. Stick and stones may break my bones but words will never hurt me.
