It's only "not helpful" because you don't have a good argument against it. :)

Also, the founders were not British. Most of them were second and third generation immigrants.

In addition, I don't think you realize how funny this statement is:

> Ethnic politics had little opportunity to arise in these communities, which were individually mono cultural

I wonder if you can spot the massive gaping hole in this logic. I doubt it.

Being born in a British colony in the early 1700s to British subject parents did in fact mean you were also a British subject. Several were also born in Great Britain proper. They were also nearly all ethnically English or Scottish.

Indeed, most of the founding fathers were British.
