Tina was great, funny, sarcastic, and insightful. Yes, insightful - but the author didn't identify some of Tina's better, more pointed retorts to prejudice. On the other hand, this author is just too full of herself and her message, lecturing a mythical white person to sit with their assumed discomfort, while slagging Tina for not telling people to get out into the street. Can you say "double standard"?
