Similar things have happened to me basically all of my academic career. When I got into an exclusive magnet high school in my city, when I got into a 5-week scholars program, when I got a scholarship to college...and many others. Each time there was someone around to basically say that I only got it because of my race when I KNOW that I worked hard to get where I am.
Another time one of my friends was complaining that she didn't into a certain pre-med scholars program because they needed to pick Indians to help with diversity. I still think about her comment all the time. She didn't for one second stop to think that maybe all those "Indians" that were picked for the program were just better applicants than she was. There was no way that the reason they were picked was that they were better, in her opinion. Ughhh
Maybe it's a coping mechanism to deal with their own rejection????
But then that's just an excuse...
