Pokémon Wooloo Racial Joke

Explain Bear here. So, you got these two Pokémon sheep, right? One's mostly white and one's mostly black. The meme creator, probably someone with a very 'edgy' sense of humor, is making a joke about racial identity by connecting the colors of the sheep to human races. They're asking a ridiculous question based on the real-world controversy about who can use a specific racial slur. You, being smart enough to get this, probably understand how people try to use shock value for comedy.
