It doesn't matter the gender, color of skin, age - the person who does that sort of thing is typically a narcissistic a-hole who is entertained with dysfunction - they love watching people scream and yell at each other and get others into trouble.
Most times, they set up their little dramas up so they can be grouped in with the "victims". Generally, they either grow out of it or learn how far they can push their fu**wadery before they start getting a reputation for it by the time they leave high school, but there are some who just can't control it, or have learned to act out this way as a coping mechanism for their own dysfunctional upbringing.
Sad it wasn't caught early enough to not make a big splash that could possibly be used to discredit real racial bigotry, but at least it was caught early enough that the clown gets kicked out and maybe gets a chance to grow the F*** up.
There's a similar pathology in those who need to be the Corpse at every Wedding or Bride at every Funeral.
