Racist taunt is precisely such name calling based on the colour of the skin or basing upon a generalisation like coolie.
Just imagine what goes thru the mind of a person who does such name calling. He only sees the skin colour and makes a quick judgement of his race or ethnicity. The only thing they can then think of is a comment like Coolie or Monkey. Now how is that not racist. They have not cared to look beyond the skin colour or race.
