Is diversity good?
Yes. Diversity keeps us alive and healthy. Isolated gene pools stagnate and become diseased.
It is a delicate balance, however. It is important for humanity to maintain a sense of identity and culture. Building walls between peoples, however, is not good for anyone. It may be hard to embrace those different from us, but from a health standpoint introducing foreign seed here and there is very beneficial for us as a species.
Are all peoples equal?
No. Through reseeding and juggling we believe all people have the potential to be equal, however. Nobody is inherently unhealthy due to their race.
