To racist, fighting with our voice is the only way we should do!

I met similar thing before with a black guy in downtown, Washington DC. He said to my coworker who is an indian guy 'go back to indian'. my coworker quickly had voice fighting with him.

That black guy is just a money colloector for a parking garage.

To these kind of trash, always be prepared to fight a few word. But before do it, try not losing our coolness entirely.
