The answer is: Native Americans had the same distaste for the customs of the settlers as the settlers had for Native American customs.

Basically, the excerpt implies that settlers and the Native Americans individually think that their manner is the basis of perfection. So, any diversion to the accustomed manners is distasteful to them. That is what he meant by: "They think the same of theirs". Because of their differing cultures, they both dislike each other.
