Tell her:
It is so low to be a racist. Racism is disgusting. It is so low (you are so low), I don't want to talk to you. Get away.
Canada is a country with all races with all skin colors, you are telling me this. You are so low. Hey everyone here, this is a racisit. She said I should not be here only because of my race and my skin color, she is so low. It is so disgusting to see this woman with so low racism speech. She is the one who does not deserve a good country like Canada. This woman is so low, I don't want to talk to her, get away
I am a Canadian who respect all the races and people with all color skins. I am a pround Canadian. She is not. (You are not.) A racist is so low, I can call 911.
如果她很凶,你可以尽量说 A racist is so low, so disgusting. (避免说You are so low ...)
