Brit's viciousness speaks to the amount of hate that she holds inside herself, which likely began when she first heard that her mother left Francis for a black man. This shows that both she and Turk lack the capacity to think critically about the tragedies their families have experienced, and instead take the easy route and blame people different than themselves. Brit never considers, for example, if Francis might've been at fault (or that one black man’s actions might not be representative of black people as a whole).
