inheriting white privilege from my adoptive parents?

Chantelle
Today my teacher was dividing the class by shoelaces. She didn't tell us until after the class but a lot of the people thought it was by race. One girl said that all the brown kids are on one side and the white people on the other. I said I'm not white I'm chinese and I'm on this side and she asked me if my parents who adopted me were white and I said yes. So in return she said so you're white then. I'm sorry I didn't realize that I inherited what ever skin tone my adopted parents have. So in that case if my parents were black then I'd be black? Just because my parents are white doesn't mean I don't face discrimination and racism. It doesn't mean that I inherit their white privilege. I just thought it was dumb and wanted to rant about how uninformed and annoying high school students can be. 
Some people think it's my teacher being racist. She was teaching a lesson on unearned privilege and how people who get that privilege can easily ignore others without it. Don't worry my teacher isn't racist, but some of the students are definitely uninformed and ignorant It was the students who were telling me that I am white my teacher didn't even hear this interaction she was busy looking at people's shoelaces to tell them where to go haha
