Racism is when you think all asian are from China. Racism is when you think Hong Kond and China are the same. Racism is you think without German you cannot work in Switzerland. I mean, when western people visit asian countries, we won’t assume their nationalities. When someone would like to work in Hong Kong, we don’t force you to know Cantonese. Basically this type of racism is when you don’t understand the world but you already have your own persective in your mind, that’s voluntary racism. Unlike the involuntary racism, you don’t mean to. However, this shows how close-minded you are. Not everything has a stereotype. Everyone is different. And nationalities do helps to understand and help you recognise different cultures. Languages and races are never the problem, peoples are.
