Have you updated your whooping cough vaccination recently? Remember, adults need a booster. Nor should you forget that immunity is not a lovely parting gift after contracting whooping cough. Whooping cough is extremely unpleasant and you do not want to have it or infect others. I speak from experience. (Moreover, since I am allergic to tetanus and therefore can't be vaccinated against whooping cough, I am counting on the herd here.)
I believe that diversity in and of itself is valuable and important. However:
Research shows that students attending racially and socioeconomically diverse schools have higher academic achievement across the board.
Neat, huh? Support diversity in schools today!
