This is our country, a war was fought and we became independent from England. The illegal immigrants should get out and stay out.
Do you question England's being a country? They were once barbarians, and fought other barbarians for land.
Do you also question that the Roman Empire was an Empire? The Romans were extremely tough, their military was the best the Ancient World had ever seen, they got most of their Empire through fighting and massacring people.
How America became a country doesn't matter. Illegal immigrants don't belong in America, this isn't their country.
The Indians fought back, we were superior. American vs Illegal immigrants, we're superior again(we should peacefully find them, and hand them over to the countries that they came from, using minimal force, and only if necessary).
