In the movie Teen Wolf, Michael J. Fox plays Scott Howard, an average player for his high school basketball team until he discovers he is a werewolf. When Scott changes into "the wolf," he becomes a star basketball player, takes his team to the grand final, and wins the regional championship. He also becomes a show-off, has women fighting over him, can sniff out hidden stashes of marijuana, and adamantly declares "I'm not a fag!" to his best friend Stiles.
The people who made Teen Wolf send out the message that to be a good basketball player, you have to be a werewolf. In the real world, which people are good basketball players? Black people. Therefore, being a werewolf is a metaphor for being a black person.
The people who made Teen Wolf are suggesting that black people are obnoxious, sex-crazed, pot-smoking, homophobic animals.
