Obvisouly thickos run off what DM said.
"On New Year’s Day, Guillot tweeted that he was giving a 3-year-old colt a “unique name in honor of a TVG analyst,” adding a Black fist emoji. When a follower asked the name, he responded, “GRAPE SODA,” which can be a racist term directed at African-Americans.
So the term itself is not racist, but when the owner used the term directly at a Black Person to cause offence then it can be seen as racist. No different than if he called his horse White Lemonade and directed it at a white person, they could rightly feel that is a racist slur directed at them.
When will thickos learn? Never it seems whilst they read the DM, SUN etc.
