Wow! I just don’t even know what to say about this one. I have sons, one who drives to make extra play money sometimes), and I never this was an issue. It’s pretty scary how even a simple unwarranted “yes” by Uber Ellen could make someone’s life a living hell. Sometimes I surprised at the overt ways racism is expressed. Sounds like your son has a great cheerleader/teacher in his corner. The only thing we can do is educate our children and try to heal the wounds racism leaves behind.
