Well, let's see here.
This continent was discovered in the late 15th century by European explorers. Then, settlers came. Then villages, towns, and cities grew. The average generation was something around twenty years. And there were several generations of Americans between the first settlers and the Founding Fathers.
The Founding Fathers were born on this continent of parents mostly born on this continent. They were Americans before there was America. They came from the thriving metropolises of Boston, New York City, Philadelphia, and others that don't come immediately to mind. A few may have been recent immigrants but the majority were not.
They certainly were not as you put it <a bunch of strangers from other lands.> This was their land. They took it from the natives just as our Texian founders took it from the Mexicans. They rebelled at rules and regulations enforced by the Monarchy and its' representatives, and when they had enough, they threw the scoundrels out.
Sounds like a good idea to me. Take your revisionist, liberal history re-writing, snide "Hey history buff....."remarks and asinine attitude and shove it.
Sheesh, if dumbass was fatal, you'd be hospice bait.
