LOL. There was no Indian nation, just a collection of individual tribes that lacked the ability to stop the influx of more advanced European settlers. The so-called native population had no immigration "policy."
There are no native Americans. North and South America were populated by migrants from the Bearing land bridge who started coming around 20,000 years ago.
Dumb comparison.
Agree. The Bering land bridge from Siberia is completely believable. The dichotomy of Leftists is striking. ‘We are all immigrants’ doesn’t include Native Americans as they are considered to be the natural inhabitants of this country. But Leftists also say things like ‘they (illegal immigrants) are more American than those of us whose families have been here for several centuries’. Immigrants must assimilate or we will become the mess that is Europe. But that’s what the Leftists want.
