I have another reason why I can't stand white parents
Why don't you like white parents?
Because, they always go on and on about how they want their children to learn something about the Chinese or Chinese history, but at the same time they won't let their own child learn Chinese at school.
You shouldn't paint all white people with the same brush. Many people are chauvinists when it comes to their own language. It's human nature and doesn't necessarily make them bad people.
Why did you think I don't want Korean people in my home? It's not wrong to want my family to speak Chinese, just like their grandparents.
That's my point -- but in your case, it sounds like you've taken the chauvinism too far.
