alt Hacker News>If you have any acquaintance with English history you would be well aware that there are native ethnic groups that have been in the UK since approximately the end of the younger dryas around 11,000 years ago.
And you'd be aware that nothing even vaguely corresponding to 'England' existed 11,000 years ago. If you are willing to lump the descendants of Romans, Normans, Jutes, Durotriges, Iceni, Vikings, etc. together into one group and call them all 'English' just because they happened to live in the territory of what is now England, then you've already conceded the point that the identity is national, not ethnic.
But hey, over in the other thread you are denying that Boris Johnson is English, so it's clear that you have a rather eccentric concept of the category.
It's interesting that other native groups, all of which have intermixed with others over thousands of years don't have to defend their right to their ethnic identity.
The English ethnic group is defined by a shared genetics and culture, the English enthic group isn't just political it is biological and can be identified via DNA.
I wouldn't consider my definition eccentric, it's based on the UN defintion: Ethnic group or ethnicity refers to a group of people whose members claim a common heritage or common ancestry and usually speak a common language and may have some common cultural practices.
The other thread argued that Boris Johnson is ethnically Turkic (I have no idea if that is true) on the assumption it is true, Boris Johnson may meet the requirement of a common language, but does not meet the requirement of a shared ancestry to be ethnically English.
Many of the groups that you mentioned existed in the UK over 1000 years ago, and shared in the same invasions, same issues, and developed a shared culture due to that shared history and closeness of relations, and of course as evidenced by DNA analysis interbreeding.
So yeah I would say that in the space of a millennium multiple groups can become one group.
