I wanted to make my new black classmate happy so I got him a gift. It was a bar of dark chocolate
Are you implying that because he has dark skin he must like dark cholocate?
No. My black classmate told me he doesn't like milk chocolate, so I got him dark chocolate and he was happy.
Good, as commenting that black folks must like dark chocolate is marginalizing to them. Imagine if people said white people must like milk chocolate.
