 The text discusses how to deal with racist comments from white friends and relatives. Schlesinger, 63, had a conversation with her husband about how to handle such situations. She argued that it's never okay to use the N-word, even if black comedians do so. A study found that almost 300 Jamaican youngsters were measured from the age of eight. When they reached 22, they were asked to undergo more tests. The results showed that those with symmetrical legs were more likely to agree with racist views. Hannah said she apologized for her remarks but Hansson said it wasn't good enough.
