If you're from the UK it's because Jamaicans made up the first large, non-white wave of immigrants to the UK while it was still mostly white, so there's a lot of racist attitudes still lingering.
F*ck this nation. Going home the first chance I get. I'm done with every other race. Strictly Jamaicans in my circle now, f*ck everybody
Then you're an idiot, you can't defeat racism with racism.
