Well you grouped "the Koreans" all into a single entity completely ignoring the individuals and support a collective "revenge" by the also grouped together entity the "black community". 

You are grouping people based only on their race and using that to cast not only judgement but collective punishments as well. That is racism.

&gt;or are you just taking a chance to call someone black racist

You being black doesn't mean shit. You can just be as racist as anyone else.
