Your source doesn't appear to agree with you.
The term 'Anglo-Saxon' did not become common until the eighth century, when people on the continent started using it to distinguish between the inhabitants of Britain and the Saxons who remained in northern Germany.
This backs up my point as well as the quotes from Ben Franklin, such as this one:
Why should Pennsylvania, founded by the English, become a Colony of Aliens, who will shortly be so numerous as to Germanize us instead of our Anglifying them, and will never adopt our Language or Customs, any more than they can acquire our Complexion.
Is the "race" component supposed to be because Franklin used the term "swarthy" to describe the complexion of the non-English Europeans such as Russians and Swedes??

I don't know. The person you need to ask that question of has been banned. I don't speak for anybody but myself.
