"I had to go through the pain of witnessing his racism with my own eyes, and hearing it with my own ears, many times, until I couldn't deny it any longer". "I'll do what I have to do to protect myself". "She worked here for a year, and didn't have any of these things to say-in fact everything she said was quite the opposite".
