i don't know if this counts to discrimination.
i've been hanging out with an american guy lately. he is not white, his dad is Italian and his mom is spanish. Once he told me, his friend, an white girl was so surprised he hangs out with me. That girl knows me too. She even couldn't believe how we can get along so well. She asked him, what you two talked about when you were hanging out. My friend told me this girl is a typical white american, all her friends are almost white.
