Those aren't anything like each other.

A jew who isn't Jewish isn't a jew. He's typically a Leftist pretending to be a jew. The core element to a jew is his Judaism. It is his culture, his language, his history, his religion, his family, his friends, his community, his home, and his... uh, well, tradition.

Britain is a political entity that is comprised of 4 kingdoms, one of which is England. An englishman is necessarily British, and that is because England is part of Britain, and an englishman's culture, language, history, religion, family, friends, community, home, and traditions are English (which are thus British).

A non-English Englishman doesn't exist. A man living in England, who is a Pakistani Muslim, who opposes the existence of England, demands the construction of an Islamic Caliphate, doesn't speak English, doesn't interact outside his Islamist community, can not be English.

Being English is core to being an englishman.

Being Jewish is core to being a jew.

Removing the core element that defines the object is to remove the definition of the thing itself.

White on the other had, like all racial constructs, is a wildly broad construct defined almost entirely within a political sphere. It has no shared religion, tradition, language, culture, history, or even geography. While biological substrata exist ("Biological Race" if you will), these don't define the religion, tradition, language, culture, history, or geography.

You can have a white englishman. You can have a white jew. You can have a black englishman. You can have a black jew. You can't have a russian englishman, nor an athiest jew.
