才有幸看到此文。不過，

你這個純種論，實在不敢苟同。

I don't know much about others, but regarding Newton, what do you mean that he has pure English blood? English as an ethnic group is derived from several tribes and ethnic groups, such as Ancient Britons, Celts (as far as you call it an ethnic group), Romans, Angles, Saxons, Jutes, Frisians, Wends, Geats, Danes (Vikings), and Normans. By the time Newton was born, the English ethnic group has been well mixed up.
