And that's where that nationalism and then eventually ultranationalism came from.

而正是从那里，民族主义最成了超民族主义。

Is that part of that ultranationalism was a certain amount of genetic and cultural pride in Japan and the Japanese.

那是超 nationalism 的一部分，即日本和日本人对自身遗传因和文化的某种自豪感。 注：原文中的 " ultranationalism" 直“超 nationalism”，但通常会直接翻“端民族主义”或“超民族主义”。根据上下文，这里使用了“端民族主义”的含义。

And there's nothing wrong with having pride in your culture, but the problem is very often, especially in the context of nationalism or ultranationalism, means everybody else is inferior.

并且以文化自豪感是没有问题的，但问题是， 尤其是在民族主义或超民族主义的背景下，这意味着其他人都是劣等的。
