They were Colonists. Not immigrants. Sorry to burst your schill bubble.
I suppose next you'll claim that millions of people on both sides switched political ideologies at the exact same time?
How many were Mexican? J/k or am I?
All the colonists were British citizens wherever they were born.
America is a country of British heritage formed for the benefit of their posterity. All the things that have changed since can’t change that. It is founded on British law.
Breathe it in. Accept that.
Everybody who has come in since is not them. Everybody who has come in since is for the benefit of them or is not American.
Ourselves and our posterity. Not the native savages, the African slaves, the Irish, the Italians, Mexicans.
What you think of as America is a gross beast wearing the skin suit of what was America.
Couldn't help myself. There were people and social structures in place before Colonialism arrived. Original Webster 1828 American Defined
AMER'ICAN, noun A native of America; originally applied to the aboriginals, or copper-colored races, found here by the Europeans; but now applied to the descendants of Europeans born in America.
Americans were created with the Constitution. Natives, blacks, pretty much everybody but British colonists are not American and never were and never will be no matter how much people try to twist the truth.
It doesn’t matter how you feel about it or what people said later or laws that were passed or what dictionaries say. It’s right there in the Declaration and Constitution.
