CA: You're saying that people of reason, people who would consider themselves not racists, but moral, upstanding people, have a rationale that says humans are just too different; that we're in danger of overloading our sense of what humans are capable of, by mixing in people who are too different.
pessoas que não se considerariam racistas, mas pessoas morais, éticas, têm um lado racional que diz que os humanos são muito diferentes; que corremos o risco de exceder nossa percepção sobre o que os humanos são capazes, ao misturar pessoas muito diferentes.
