To go a step further, moral disagreement doesn't require a language barrier at all.

"We and abolitionists are talking about a different subject matter and it is an error of the "computer translation programs" that the word comes out as "morality" in both cases. Morality is about how to create a proper relationship between races, everyone knows that and they happen to be right. If we could get past difficulties of the "translation", the abolitionists would agree with us about what is moral, we would agree with them about what is abolitionism."
