Genuine Question
So, I'm a teenage girl who's of Asian descent. And I was genuinely wondering if black people could be racist? There's this girl in my grade who's of African descent and is extremely rude/racist towards my other Asian friend and me. She's completely nice and kind to my white friends, but when it comes to me and my friend, she makes sly comments. My friend and I have asked her to stop multiple times, but she doesn't listen. She makes fun of our skin tone, our eyes, our food, etc. She even told my friend that she needs to go back to her own country, which is ironic as she isn't even an American citizen, while my friend is. She discredits any achievements (academically) that me and my friend acheive and says that it's "in our genes". She makes comments about my friend and me looking identical and being able to speak "our" languages to each other. My friend is Chinese; I'm Korean. We don't speak the same language. I do not speak Korean, but my friend speaks Mandarin with her family. But if she hears my friend speaking Mandarin, she just starts to speak gibberish and says that it's the same. As I said before, we have told her multiple times we're uncomfortable with the comments, that we really don't like the comments, and that we want her to stop. She hasn't, so we went to our school counselor. She basically told us to stop making stuff up, that black people are incapable of being racists, and that we were being unnecessarily rude and making stuff up. She told us that if we talked about this again, we'd be facing disciplinary action. So, I'm confused: am I being too insensitive, and is it impossible for black people to be racist?
I'm sorry if this comes off as insensitive; I'm just genuinely curious.
