Why is having a racial preference racist when you can choose who you want to date?

Because an actual racist says it is. To some you can say "black eye" or "white beans" and you're a racist. Ignore them. They dont want racism to end. They would be lost if they couldnt race bait or accuse someone else of it. Its just a preference like tall...or short...or skinny over curvy....or red heads. People have preferences. Period
