It's not going to be lengthy. I'll clean it up for you.

1. Settlers are not immigrants. This country was not created by immigrants to Pequot or Sioux countries. There were no countries. They were wandering nomads. You cannot "immigrate" to undeveloped woodland. Settlers built this country.

2. "Your ancestors were immigrants" does not mean "any immigrant from anywhere is equally fit to live here." There are actually very clear court cases in early US immigration law where individuals were either granted or denied admission to the country based on how much they could blend in with the native British/English population. They accepted a Polish man and denied and Indian man because the Pole was similar enough and the Indian wasn't.

This shouldn't be hard for you figure out by yourself, so we can conclude that you're either stupid or dishonest
