For 10 years, the Southern Poverty Law Center has sponsored Mix It Up at Lunch Day, an anti-bullying initiative in which school children are encouraged to break out of their normal social cliques and eat lunch with someone they might not normally sit next to. The program is designed to lessen bullying by making kids familiar with different types of people. Over 2,500 schools now participate in the program. Surely that's something everyone can agree is a good thing, right?
